UK Royal Marines Commandos Adopt SIG Sauer MCX

The UK’s Royal Marines have confirmed that some units of the UK Commando Force are now equipped with the SIG Sauer MCX. The announcement on social media simply read: “The UK Commando Force has been issued with 1,500 new Sig Sauer MCX rifles for use in the maritime counter-terrorism role.” These are set to be used alongside the new Knights Armament-produced KS-1s which were adopted in 2023 as the L403A1.

The first confirmation that the MCX was in British service came in February, with the publication of a video titled ‘RAID’ showcasing the Royal Marines Commandos’ capabilities. In the video members of 42 Commando are seen using SIG MCX LTs while Marines from 40 Commando are seen using the L403A1, which has been adopted by elements of the UK Commando Force and the new Army Special Operations Brigade, which is made up of the battalions of the Ranger Regiment which was formed in 2021. Check out my earlier article/video looking at the L403A1 here.

In a full statement the Royal Navy, under which the Royal Marines operate, said the procurement was “part of £6m Navy investment” with the new rifles “designed to complement the Commandos’ new general use weapon [the L403A1].”

This means that the UK Commando Force have at least four AR-patterned (in terms of ergonomics and layout) carbines in service: the new MCX variant, the L403A1 (KAC KS-1), and the L119A1/A2 (Colt Canada C8) which is available in a standard configuration with a 15.7 in barrel and in the C8SFW configuration which has a CQB upper receiver with a 10 inch barrel. Additionally, they also deploy the 7.62x51mm AR-10-pattern L129A1, with plans in the works for an A2 chambered in 6.5 Creedmoor.

Lieutenant Colonel Olly Osborne, of the Commando Force Programme team, said: “These rifles reinforce the commitment of the Navy and Defence to our transformation, and the value the Commando Force provides to our national and international security. This is an excellent period of investment in the force and provides great confidence through exceptional task specific modern weaponry.”

The rifle was procured under the auspices of Project Hay, during which the Royal Navy says that Commandos “put the system through strenuous testing during force-on-force exercises and live firing drills… [they were able to] thoroughly field-test systems and provide feedback on their performance. This was instrumental in shaping the final configurations of the fielded MCX.”

A different configuration of the MCX LT was previously part of the Project Hunter trials. The Royal Marines Commandos’ MCX will replace the short C8SFW with trials of a .300BLK upper and associated ammunition said to be ongoing. This will likely be used in conjunction with reduced ricochet, limited penetration ammunition.

At SHOT Show 2025, SIG Sauer had one of the rifles on display but couldn’t offer details at the time.

From the released imagery we can see that the rifle, an MCX LT, seen at SHOT 2025 matches. The rifle has a 12.5in barrel and is equipped with a SIG Romeo 8T red dot sight and Juliet magnifier, mounted on a UK-marked mount, as well as a SLXC compact suppressor.

In addition to the 5.56x45mm chambering the Royal Marines will also field a .300BLK configuration which has a 9in barrel and accessories (including the stock, an SLX762QD suppressor, magazines, rail scales and optics) in black finish while the 5.56x45mm chambered carbines all feature FDE-coloured accessories (as seen above). This system is intended to prevent the mix up of ammunition between the two weapon systems preventing accidents. As with the earlier L403A1 procurement the MCX carbines were procured via UK-based Edgar Brothers.

UK Commando Force is made up of a number of specialist units; 42 Commando, the unit seen equipped with the rifles in the RAID video, specialises in Maritime Security Operations, Maritime Interdiction Operations, Joint Personnel Recovery, Support and Influence Operations, and Ships Force Protection Teams.

42 Commando won’t be the only unit to deploy the new rifles. UK Commando Force Operations confirmed that L403A1 Alternative Weapon System (AWS) is the primary weapon for 40 Commando and 45 Commando, and the Commando Force’s Surveillance and Reconnaissance Squadron (SR). The latest figures from the UK MoD confirm that delivery of 1,620 carbines have been completed. but that the MCX will also equip 47 Commando Raiding Group. Other UK Commando Force elements will retain the Colt Canada C8, with the aim of replacing remaining SA80 series weapons currently in use.

In a recent article Soldier Systems Daily, who has a close relationship with SIG Sauer, noted that the procurement of the Royal Marines’ MCX-pattern carbines had been carried out two years ago with delivery completed in 2024. The Royal Navy’s announcement did not state what the weapons’ designation is but several models of MCX have been in UK service for a number of years, largely within the ecosystem of UK Special Forces. Sources suggest that these MCX are designated the L143A1 and L143A2, it remains to be seen if the new rifles will be designated the L143A3 or be classified as A2s.

Most recently, UK Commando Force shared several photos and a short video of the MCX at the range, with a Royal Marine demonstrating how the weapon can be fired with the stock folded. This is a useful feature for operating in confined spaces during boarding operations.

Malta’s Service Rifle: The AK

A comment in my recent video about the Royal Bermuda Regiment’s use of the Mini-14 sparked my interest. It noted that Malta, another small island military, uses the AK. I wasn’t aware of this so I decided to do some research.  

Malta’s military, known as the Armed Forces of Malta (AFM) is roughly the size of a brigade. In recent years the Armed Forces of Malta have had a strength of between 1,600 and 1,800 personnel. It has three battalions a maritime squadron and an air wing. Malta is a neutral nation and as such the AFM’s role is territorial defence, internal security and border control.

Malta gained independence from the UK in 1964 and became a republic in 1974, this is when the AFM was founded. With the former link to the UK much of the AFM’s initial equipment was of British origin and the 7.62×51mm L1A1 Self-Loading Rifle was used as the AFM’s service rifle for many years this appears to have changed in the late 1970s early 1980s. The FN FAL-derrived L1A1 is still used as the AFM’s standard drill and parade rifle.

The AFM celebrated its 50th anniversary in 2020 and shared this time line of their uniform and equipment in their service magazine On Parade which gives us some idea of how their small arms changed over time. We can see that the AK-pattern rifles have been in service since at least the 1980s. 

The AFM’s website lists their small arms with personnel being armed with Beretta 92s, a variety of HK MP5s, and what they describe as the ‘AK 47 Variant’. The site lists the rifles as being manufactured by Russia, Romania, China and East Germany. These rifles are all chambered in the 7.62×39mm cartridge.

Where the first AK-pattern rifles came from is unclear, although one source suggests the German and Romanian rifles were bought second hand in the 1990s. From a survey of images and video shared by the AFM in recent years it appears that East German MPiKMS, Romanian PM md.63, North Korean Type 68 and Chinese Type 56/II are in service.

The origins of the Chinese rifles is easy to trace back to a 2003 donation of small arms and light weapons made by the People’s Republic of China. An agreement was signed with China in June 2001 and as part of this a donation of 150,000 Maltese lira-worth of weapons. By 2003, however, it was reported by the Time of Malta that this had increased to 500,000 Maltese lira-worth of weapons. This included Type 56/II rifles, Type 80 general purpose machine guns and RPG-7 clones. The AFM’s acting commander Colonel Carmel Vassallo described the donation as a “dream come true” at the time. It reportedly allowed the entire AFM to be armed with a single type of service rifle.

The reasoning behind the adoption no doubt comes down to financing, Malta being a small island nation does not have an extensive defence budget, reported at 54 million Euros in 2020, and perhaps have chosen to prioritise personnel and procurement of naval and aviation assets over small arms. It is easy to see how the donation of service rifles and other small arms would be welcomed when balancing a modest budget.

AFM personnel with modified AKs (AFM)

Over the last 10 years there have been a number of photos and videos released showing AKs which have been upgraded with some aftermarket modifications. The mods appear to predominantly be sourced from FAB Defense – with their CAA Polymer buttstock and VFR-AK railed forend with a top rail which extends over the top of the receiver cover. This provides the bare bones AKs with some modularity. It’s unclear how widely issued the modified AKs are but from officially release imagery it seems that the basic AK-pattern rifles are more prevalent. In recent years Malta has stood up quick reaction forces and it appears from videos and images shared of the company that they have been equipped with SIG Sauer MCX rifles.
