Does the L403A1 Mount a Bayonet?

In a recent article/video we looked at the UK’s newly selected Alternative Individual Weapon system, the L403A1. The Knight’s Armament KS-1 was selected as the new rifle for the Ranger Regiments of the Army Special Operations Brigade and for elements of the Royal Marines Commandos.

One question which frequently appeared in the comments was “can it fit a bayonet?” This is a good question because the British Army is known to be a proponent of bayonet use with a long history of using it to great effect from the 1600s right through to recent conflicts in Iraq and Afghanistan.

*Surveillance and Reconnaissance Squadron member with new L403A1 (Royal Marines Commandos)*

The short answer to the question is – yes. The longer answer is a bit more complex. Just a week after the selection of the new rifle was announced Knights Armament displayed one of the rifles with a bayonet fixed at the DSEI 2023 exposition in London. This naturally caught some attention.

*L403A1/KS-1 with a bayonet seen as DSEI 2023 (via social media)*

However, when the selection of the L403A1 was initially announced a breakdown of the Alternative Individual Weapon system’s accessories and ancillaries was released. This included: a Vortex 1-10x LVPO, an Aimpoint ACRO and a QDC/MCQ-PRT [Quick Detach Coupling/Mini Close Quarters–Pressure Reduction Technology] suppressor along with a sling, a vertical front grip, and a Surefire weapon light but noticeably it did not include a bayonet.

*Breakdown of the parts and accessories adopted with the L403A1 (Edgar Brothers)*

The ability to fix a bayonet was not part of the weapon’s original requirements and it was not stipulated by the Rangers or Commandos. Instead, Knight’s Armament developed the capability themselves, perhaps recognising the UK’s fondness for the bayonet and the British Army’s long history of its use as both a training aid and as a weapon of war.

*KAC’s 1st bayonet design with QDC attachment mechanism (courtesy of Gregory Knowles)*

TAB reached out to Knight’s Armament about the bayonet and they confirmed that “the bayonet was designed in anticipation of a potential need, though not required as part of the contract.” The bayonet seen fixed to the rifle at DSEI was apparently the first iteration of the design which according to Knight’s Armament “used the same mounting mechanism as the suppressors” but a new “revised design uses an attachment mechanism that is more similar to the SA-80 bayonet attachment/retention design.”

Essentially, rather than using the suppressor’s ‘Quick Detach Coupling’ system the newer iteration of the bayonet uses a pivoting catch. The quick-detach method used by the suppressor involves the suppressor being rolled one way until the index pin seats in a notch before tightening it by twisting it the other direction.

*Photos of 2nd bayonet design (Knight’s Armament Company)*

The new iteration of the bayonet fits over the rifle’s 3-prong QDC muzzle device and uses the same style of catch system as the SA80. Knight’s Armament explained that “the redesign was a refinement of an initial concept after some basic testing and feasibility evaluation.” The bayonet haven’t undergone any serious testing as they’re still in the development phase. A chromed version of the latest iteration of the bayonet was also displayed at DSEI and has a removable pommel piece that can act as a small storage space and makes the bayonet more comfortable for use as a knife.

The bayonet’s blade is offset to the left side with a corresponding hole which lines up with the muzzle.

While bayonets aren’t currently planned to be issued with the rifles, the requirement might develop once they enter service. If, in the future, the UK Ministry of Defence requested a bayonet for the new rifles it seems that Knight’s Armament could be able to oblige.

Project Hunter: The UK’s New Assault Rifle

The United Kingdom has announced the selection of the Knight’s Armament Company KS-1 as the new individual weapon for the new Ranger battalions and the Royal Marines Commandos. The requirement for the new rifle was released back in August 2021, and called for the “procurement and support of an Armalite Rifle (AR) platform Alternative Individual Weapon (AIW) System.”

The requirement called for a ‘Rifle System’ which comprises the weapon and a ‘Signature Reduction System’ [suppressor] and an ‘Optic System’. The rifle itself had to be ‘gas operated with a rotating, locking bolt’ and was to specifically have “a standard configuration, not bullpup, with the magwell in-front of the trigger housing.”

*Royal Marines Commando with L403A1 (Royal Marines/Royal Navy)*

The UK launched Project Hunter to select a new Alternative Individual Weapon (AIW) to replace the SA80/L85 series of rifles and Colt Canada L119s in service with the Rangers and elements of the Royal Marines Commandos. After two years of competition the UK MoD has announced that Knight’s KS-1 has been selected as the L403A1, beating off reported competition from Heckler & Koch, SIG Sauer, Daniel Defense and Glock.

Other weapons believed to have been evaluated include the HK416A5, the SIG Sauer SPEAR-LT, the Daniel Defense M4 and Glock’s GR-115F. Other companies believed to have submitted rifles include Colt Canada, Lantac, Haenel and Steyr amongst others.

The new rifles will supplement the L85A2 and L85A3 which currently equip the majority of the UK armed forces. The rifles will be procured via UK-based company Edgar Brothers and the £90 million ($110 million) contract will see up to 10,000 new rifles delivered over the next decade. An initial £15 million order for 1,620 AIW systems has been placed with the British Army fielding them with the Army Special Operations Brigade, with the brigade expected to receive the first rifles by the end of 2023. The Royal Marines’ ‘strike companies’ and Surveillance and Reconnaissance Squadron will also be among the first to receive the L403A1. The ‘Alternative Individual Weapon’ essentially fulfils the same role every AR-pattern rifle in UK service has since the 1960s.

*New Alternative Individual Weapon – L403A1 (UK MoD)*

The UK’s Minister for Defence Procurement, James Cartlidge said:

“This is another example of how we are committed to investing in the most advanced battlefield equipment to back our troops on the battlefield. This advanced rifle’s ability to help soldiers maintain the stealth edge not only protects them but delivers war-fighting advantage over our adversaries.”

Interestingly, the UK Ministry of Defence’s press release emphasises that as an AR-pattern rifle the L403A1 “shares much in common with the rifle systems used by many of the UK’s allies. Given their specialist role, and the critical task of working with and alongside many of the UK’s allies, the platform will enable ASOB to share skills and drills in an efficient manner.”

*Close up of the Vortex and Aimpoint optics which make up part of the AIW package (Royal Marines/Royal Navy)*

So what does the Alternative Individual Weapon (AIW) system include?

The system builds around the Knight’s KS-1 but also includes a magnified 1-10 LPVO optic from Vortex, an Aimpoint ACRO P-2 red dot and the Knight’s QDC/MCQ-PRT suppressor. The prime contractor for the project, Edgar Brothers, are responsible for the sourcing and assembly of the AIW’s accessories. Accessories for the rifle will include a MAGPUL M54 sling, a Surefire Mini Scout Light Pro, G10 rail scales and a MAGPUL M-LOK AFG.

*Anatomy of the L403A1 (Edgar Brothers)*

The KS-1 is the latest iteration of the SR-16 series, it has a 13.7in (35cm) barrel and weighs 6.88lbs (3.1kg) unloaded, its overall length is 32.2in (82cm) with the stock collapsed and 34.2in (87cm) extended. The QDC/MCQ-PRT weighs an additional 13.9oz and adds just over 2 inches to the weapon’s length. The rifle uses a direct gas impingement system (or more correctly described as Stoner’s internal piston system).

The selection of the new rifle forms part of the Royal Marines’ larger modernization push under the Commando Force Programme alongside a new helmet from Gentex and Fused Binocular Night Vision devices from L3Harris.

*Surveillance and Reconnaissance Squadron member with L403A1 in Norway (Royal Marines/Royal Navy)*

We got our first indication of the KS-1’s selection in June, when the Royal Marines published a new recruitment advert featuring the rifle. It was also subsequently seen during a demonstration at Lulworth Ranges in July.

UK MoD Defence Imagery has shared some interesting photos & video from the recent Demonstration at Lulworth Range.

What caught my eye were some of the Project Hunter carbines in use. In this clip we see both the Knights Armament KS-1 AND the SIG Sauer MCX Spear-LT.

While the British military have used AR-pattern rifles since the 1960s in various roles, Project Hunter and the Alternative Individual Weapon represents a major procurement and it remains to be seen how it will influence Project Grayburn – the effort to select a replacement for more than 150,000 SA80s.

Ukrainian Troops Train with G36s

We’ve previously looked at Ukrainian troops training with the British L85A2 and Chinese Type 56s AK-pattern rifles. In June, the first images of Ukrainian troops training with G36s emerged, shared by the Lithuanian Ministry of Defence.

The baltic nations of Lithuania, Latvia and Estonia have been staunch supporters of Ukraine’s and Lithuania’s military has been providing training of various sorts since 2015. Back in April, Lithuania’s Chief of Defence Lieutenant General Valdemaras Rupšys announced that Lithuania would train an undisclosed number of Ukrainian troops on how to use various anti-tank weapons at locations within Lithuania. There has so far been no imagery released of this training.

Lithuania’s Military Academy has also provided a distance learning course online for junior leaders and at the end of October it was announced that 120 junior officers had received training across 4 two-day courses.

In the summer an in-person course that has seen Ukrainian personnel travel to Lithuania for training was established. A course at the Division General Stasys Raštikis Lithuanian Armed Forces School ended in early June. The four week course included weapons handling and marksmanship, map training, fieldcraft and tactics. Organised as part of the NATO Defence Education Enhancement Program (DEEP) it was during these courses Ukrainian personnel have been seen training with Lithuanian G36s.

*Ukrainian troops training in Lithuania (Lithuanian MoD)*

Additionally, Lithuanian instructors have also been training Ukrainian personnel in other countries including the UK. It was announced on 19 October, that a team of military instructors formed from members of the Lithuanian Armed Forces Great Hetman Jonušas Radvila Training Regiment, Division General Stasys Raštikis Lithuanian Armed Forces School, General Adolfas Ramanauskas Warfare Training Centre and the Military Medical Service had joined a multi-national training effort providing basic military training for Ukrainian troops at bases in the UK.

In mid November it was announced that instructors from Ukraine had also taken part in an international instructor course. The course reportedly covered training techniques, weapons training, instruction organisation. The Lithuanian Ministry of Defence also noted that throughout December, there had been more specific courses for Ukrainian personnel on CBRN-contaminated operational environments, courses on UAVs and on intelligence collection from open sources.

Summarising the training provided the Lithuanian Ministry of Defence said 18 different courses had been delivered including: basic individual skills, junior officer command, instructor, special forces, demolition and demining courses. Operators and maintenance for different types of military equipment were also trained.

Lithuania adopted the HK G36 in 2007 and has used several variants including the G36KV1 and the G36KA4M1. None of the photographs show the rifles mounted with optics and in three of the photographs the rifles can be seen fitted with Heckler & Koch’s adjustable blank firing attachment for the G36.

In early December Lithuania announced that in 2023 training of Ukrainian troops would be stepped up with 1,100 personnel to be trained in Lithuania. Part of the courses scheduled in 2023 will be a part of the new European Union’s Military Assistance Mission Ukraine (EUMAM Ukraine).

Bermuda’s Unique SA80

In 2015 the Royal Bermuda Regiment began to field the British L85A2 bullpup. Bermuda is a British Overseas Territory and is one of several territories to have its own British Army-affiliated home defence regiment.

The regiment’s transition to the L85A2 was completed in early 2016, with the replacement of the last Ruger Mini-14s which had been in service since 1983. If you haven’t seen our earlier video/article looking at the Royal Bermuda Regiment’s Mini-14 service rifles, do check it out.

*A Royal Bermuda Regiment recruit with a Mini-14, c.2012 (RBR)*

The search for a weapon to replace the Ruger began in the 2010s with the German Heckler & Koch G36 and the US M4 both being tested. The HK G36 was reportedly selected but budget constraints saw the British L85A2 adopted instead.

*A Royal Bermuda Regiment recruit at the range with an L85A2 (RBR)*

Reports suggest that 400 rifles were transferred along with 1,600 magazines, while over 400 ACOGs and red dot sights were also donated to the regiment by the British government. News reports at the time stated the value of the donated equipment was $1.4 million.

The Bermudan L85A2s have a somewhat unique configuration. The rifles appear to have a mix of the original L85A1 hand guards and the HK-designed conventional L85A2 plastic hand guards which were designed to be more durable. The older, original, hand guards are reportedly replaced at the unit level when they are broken.

*Comparison of the old and newer rail-less plastic hand guards*

The newer style of hand guard can be identified by its four rather than two hinges on its top portion, which allows access to the gas system, and by the slight slope forward at the front of the hand guard compared to the original.

*An RBR L85A2 is handed back into the armoury, c.2017 (RBR)*

Many associate the A2 configuration with the Daniel Defense railed forend but these are only introduced as an urgent operational requirement for operations in Afghanistan in 2009.

*A member of 26 Engineer Regiment with the Brigade Reconnaissance Force in Afghanistan in 2009 with an L85A2 TES with an ACOG/red dot combination (UK MoD/Crown Copyright)*

Interestingly the Royal Bermuda Regiments rifles all appear to have been provided with Trijicon ACOGs, previously most commonly seen on what became known as the Theatre Entry Standard (or TES) upgraded L85A2 rifles. These optics replaced the original 4x SUSAT (Sight Unit Small Arms, Trilux) and in 2011 were in turn replaced by ELCAN SpecterOS 4× Lightweight Day Sights (LDS). TES represented a new base-line standard for configuring the rifle for front-line service rather than being a new iteration of the weapon itself.

*An RBR L85A2 with an original hand guard and ACOG at the range (Royal Bermuda Regiment)*

The Bermudan rifles have a riser Picatinny rail for mounting the optic on the rifle’s original NATO-spec (non-1913 Pictatinny) rail, this was initially developed for British issued TES L85A2s. In British service the ACOG had been procured first for special forces use and subsequently as a wider urgent operational requirement where it was paired with L85A2s, L86A2s and L110 FN Minimi.

*Recruits introduced to the L85A2, note the sight riser with ACOG mounted (RBR)*

On top of the ACOG is a CQB red dot sight, this appears to be an early Shield Mini Sight Reflex optic housed inside a sight protector. The ACOGs donated to the Royal Bermuda Regiment probably came from surplus stores.

*Royal Bermuda Regiment soldiers at the range, 2021* (USMC)

We can see on some of the photos released by the regiment that the ACOGs are marked ‘IW-LSW’ indicating that they were procured to be paired with the British Army’s L85 Individual Weapon and the L86 Light Support Weapon.

Other British Overseas regiments, like the Royal Gibraltar Regiment or the Falkland Islands Defence Force, are also equipped with L85A2s but their configurations typically use older SUSATs or the newer ELCAN Specters which suggests that the Royal Bermuda Regiment’s configuration is somewhat unique.

Ukrainians Training with SA80s

In a recent video/article we looked at the AK-pattern rifles that the UK Ministry of Defense has procured to train Ukrainian troops with in the UK. In that video I touched on the use of British SA80/L85 pattern bullpup rifles used during the training of the Ukrainian troops. With fresh imagery it seems that the British rifles are playing a significant role in training the Ukrainian personnel at several training centres across the UK.

*Ukrainian soldier seen with an SA80A2 with SUSAT during training, when visited by the Prime Minister in late-July (UK MoD/Crown Copyright)*

The SA80 rifles were first seen in the initial imagery released around the announcement of the training scheme but have appeared again since. They featured in photographs of Defence Minister Ben Wallace’s visit in early July and again a couple of weeks later during another visit by General Sir Patrick Sanders’, Chief of the General Staff. The rifles were seen with iron sights and fitted with blank firing adaptors. Interestingly, at least some of the Ukrainian personnel have been shown how to field strip the British rifles.

*Deputy Defence Minister of Ukraine Volodymyr Havrylov with visits Ukrainian troops training in the UK, 19 July (UK MoD/Crown Copyright)*

On 19th July, imagery from a visit by the Deputy Defence Minister of Ukraine, Volodymyr Havrylov, also showed Ukrainian troops equipped with SA80A2s fitted with blank firing adaptors. As before the rifles were not fitted with optics.

The Ministry of Defence has confirmed that while AK-pattern blank firing adaptors have been procured, SA80’s with blank firing adaptors have also been used to ‘maintain strict safety conditions for both British and Ukrainian soldiers during training and to meet the urgency of the training requirement.’

*Ukrainian troops field stripping and cleaning SA80A2s in early July (UK MoD/Crown Copyright)*

Because the rifles don’t have railed forends some thought they might be the earlier SA80A1s. We can tell that these rifles are SA80A2s from the up-turned scalloped tear drop charging handle which also doubles as a brass deflector. The rifles have the non-railed green polymer handguards fitted. While the Daniel Defense produced railed forends have come to characterise what many thing is the A2 configuration, these were actually developed in response to an urgent operational requirement for troops deploying in Afghanistan. Many of the rifles overhauled by HK to the A2 standard retained the classic green handguards. Some, like those recently provided to the Royal Bermuda Regiment, actually have a green handguard designed by HK.

Prime Minister Boris Johnson visits Ukrainian troops (Andrew Parsons/No.10 Downing Street)

We can easily identify British troops involved in the training, as we can see that they are equipped with the new SA80A3 with the characteristic new MLOK forends and Cerakote finish.

On the 21st July, the UK Prime Minister’s office released photos and video of Prime Minister Boris Johnson’s visit to Ukrainian troops training in the North East of England. The imagery showed Ukrainian troops training in urban combat, known by the British Army as Fighting In Built Up Areas or FIBUA. This supports the theory that they are being issued for FIBUA and field exercises that require blank firing. Unlike in the earlier imagery the Ukrainians were armed with SA80A2s largely equipped with SUSAT sights.

Ruger Mini-14: The Royal Bermuda Regiment’s Service Rifle

Formed in 1965 the Royal Bermuda Regiment (RBR) is a territorial line infantry battalion, whose primary role is internal security. The regiment is essentially a territorial or Army Reserve battalion with around 600 part-time troops. Bermuda itself is a British Overseas Territory and is one of several territories to have its own British Army overseas regiments. Initially equipped with the British Army’s L1A1 self-loading rifle, the Mini-14 was selected by the Royal Bermuda Regiment in 1983 to replace the L1A1. The 1980s saw a number of other British Army affiliated units move away from the L1A1, with the Falkland Islands Defence Force selecting the Steyr AUG.

The Mini-14 GB (Government Barrel) semi-automatic rifle was purchased from Ruger. The Mini-14 GB had a thicker profile barrel with a a flash hider and mounting lug for the US M7 bayonet. The Royal Bermuda Regiment issued the Mini-14s with 20 round magazines. They were initially shipped with standard wooden stocks but in the early 1990s black polymer stocks with pistol grips were procured from Choate. Another unique attribute of the Regiment’s Mini-14s is the regimental crest stamped on the left side of the receiver. Less than a thousand rifles were produced for the Royal Bermuda Regiment.

In terms of drill with the Mini-14 it is unclear what drill the RBR adopted with the wooden-stocked rifles though it likely drew on British Army drill with Lee-Enfield pattern rifles. Since the refitting of the rifles with the Choate stock it appears that the Regiment adapted the drill laid down for the L1A1. Both rifles have pistols grips, long butt-stocks and exposed barrels which project from the forend.

*A Royal Bermuda Regiment recruit reassembling a Mini-14, c.2012 (RBR)*

The Mini-14 was developed in the late 1960s by L. James Sullivan and William Ruger, chambered in .223 Remington / 5.56x45mm it is a gas operated rifle with a rotating bolt. The rifle was essentially developed as a scaled-down M14 with a cast receiver and a simplified gas system and bolt.

*Soldiers of the Royal Bermuda Regiment, c.1993, (Seán Pòl Ó Creachmhaoil)*

The search for a weapon to replace the Ruger began in the 2010s with the German Heckler & Koch G36 and the US M4 both being tested. The HK G36 was selected but budget constraints saw the British L85A2 adopted instead. In 2012 the Royal Bermuda Regiment had entered into an agreement with the UK’s Ministry of Defence procurement office to allow purchase of some equipment such as the new Multi-Terrain Pattern (MTP) uniforms which replaced Combat Soldier 95 DPM uniforms. It was announced that in the future other personal equipment including boots, body armour and webbing could also be procured via the UK procurement system. This closer cooperation likely paved the way for adoption of RBR configuration L85A2s. The rifles, along with 1,600 magazines and over 400 ACOGs were donated to the regiment. News reports at the time stated the value of the donated equipment was $1.4 million. The switch to the L85A2 began in 2015 and was completed in early 2016.

The rifles appear to have the HK-designed conventional L85A2 plastic hand guards instead of the 2009 A2 configuration which saw the instillation of the Daniel Defence railed forend. The SUSAT sight has been replaced by an ACOG, most commonly seen on what became known as the Theatre Entry Standard (or TES) upgraded rifles. The Bermudan SA80 has a riser picatinny rail for mounting the optic, this was initially developed for British issue L85A2s. In British service the ACOG had been procured earlier first for special forces use and subsequently as a wider urgent operational requirement.

On top of the ACOG is a CQB red dot sight, the ACOG has subsequently been replaced in British service by the ELCAN Spectre. The ACOGs donated to the Royal Bermuda Regiment probably came from surplus stores. We can see on some of the photos released by the regiment that the ACOGs are marked ‘IW-LSW’ indicating that they may have previously been paired with the British Army’s L85 Individual Weapon and the L86 Light Support Weapon.

*A Royal Bermuda Regiment recruit at the range with an L85A2, note the IW-LSW marking on the side of the ACOG (RBR)*

The Royal Bermuda Regiment’s intriguing use of the Mini-14 represents one of the few military procurements of the rifle.
