Mk14 EBRs in Ukraine

In an earlier video/article we examined the M14s which appeared in Ukraine back in March 2022, since then there have been a number of intriguing sightings of what, at a glance, appear to be Mk14 Enhanced Battle Rifles or M39 Enhanced Marksman Rifles. The EBR and EMR emerged during the Global War on Terror in the early 2000s as an improved variant of the 7.62x51mm M14.

The project to develop a more compact, improved M14 reportedly evolved from a request from US Navy SEALs in 2000 for a rifle for Arctic warfare. This eventually developed into what became the Mk14 EBR with development led by Naval Special Warfare Centre Crane and input from commercial specialists and manufacturers including Smith Enterprise, Inc. and Sage International. The result was a rifle with a 18 inch barrel and new flash hider, with changes to the operating rod guide, a new stock chassis and a raft of accessories. A number of different variants were built including the Mk14 Mod 0, Mod 1 and Mod 2, the M14 EBR-RI and the USMC’s M39 EMR. In total between 2003 and 2011 just over 9,000 of these upgraded variants were assembled.

Given the significant number assembled and the fact they have been replaced by rifles such as the M110 Semi Automatic Sniper System (which has already been seen in Ukraine) and the M110A1 CSASS it would not be unsurprising to see Mk14 EBR variants turn up in Ukraine.

Over the past two years I’ve been tracking sightings of what appear to be Mk14 EBR variants but on closer examination some of them are not what they initially seemed to be, several were in fact kit builds using the standard configuration M14s which reached Ukraine in early 2022. Some, however, do appear to be surplus Mk14s.

*Yuri’s Mk14 EBR clone at the range (Nucking_Futs_Yuri)*

First, let’s examine some of the kit builds seen in theatre. The first appears to have been assembled by Nucking_Futs_Yuri, an American volunteer who enlisted in the Ukrainian Army in early 2022. Yuri explained to me that in late 2022, following combat experience where he wasn’t satisfied with how well 5.56x45mm suppressed a Russian position he decided to assemble an EBR clone using a donated chassis. Yuri noted that parts for the rifle began to arrive in December 2022 and by January the rifle had been assembled. Yuri was seen with the rifle in numerous photographs and in several configurations. It had a standard 22 inch barrel, a Sage International M14ALCS chassis and a M14DCSB (Detachable Cantilevered Sight Base). He mounted a 1.5-6x Elcan SpectreDR optic on the rifle, opting for more of a battle rifle-style set up. The rifle was damaged in February 2023 by a Kornet ATGM blast which bent both the barrel and the chassis.

In early May 2023, another rifle which resembled an M14 EBR-RI, with a 22in barrel and a black Sage International M14ALCS chassis, appeared in use with a member an International Legion team. This individual and his rifle was seen again in May 2024 appearing in a number of interviews with Ukrainian media. His callsign was revealed to be ‘Solo’ and he was described as a marksman and a squad leader with a unit of the International Legion’s 3rd Special Purpose Battalion. In the interview he explained that the rifle has originally been a wooden stocked M14 converted with a SAGE chassis sent to him by a friend in the US. Interestingly, between May 2023 and May 2024, it appears the rifle’s set up has evolved with new FDE rail covers added and a short tan Kydex handguard replacing the initial black longer handguard. These parts were likely acquired in Ukraine.

Most intriguingly, in November 2023, the first Mk14 Mod 1 appeared. Mod 1s are characterised by their shorter 18in barrels, a Sage M14ALCS/CV-BS with Magpul CTR FDE stock (with a cheek riser) mounted on a buffer tube extension rather than the earlier collapsing stock. The rifles also have LaRue LT-608 extended Picatinny risers and short tan handguards. The rifle is equipped with a Schmidt & Bender PMII 5-25×56 scope.

The Mk14 Mod 1 was assembled at NSWC Crane in 2006, around 500 were assembled. The shorter barrel and the general configuration of parts and accessories suggest that this may be a surplus rifle transferred by the US.

*A recent sighting of a Mk14 Mod 1 EBR (via Tysk)*

Most recently, on 18 October, Ukrainian telegram channel Tysk shared a series of photos of a Ukrainian combatant at the range with another Mk14 Mod 1. This rifle’s parts and accessories closely match those assembled by Crane for the Mod 1, including: an 18in barrel with a SureFire FH762KM14 muzzle device, a TangoDown BG-16 FDE pistol grip, a Sage M14ALCS/CV-BS with a Magpul CTR FDE stock (this time without the cheek riser), a TangoDown BGV-MK46 FDE vertical foregrip, and a TangoDown ACB-4 FDE bipod. The rifle is also equipped with a NightForce NXS 2.5-10x24mm optic and a DOCTER MS01 3.5 MOA red dot sight which were selected to be paired with the Mod 1. [It has been noted that the Mod 1s may also be clones due to some small differences in the chassis profile and accessories used – for instance the model of VFG, scope rings, cheek riser, and the machining on the chassis. If this is the case someone has gone to an improbable amount of trouble to ‘clone’ a Mod 1, a considerable level of effort to expend in a war zone. Thanks to tanodized for input.]

From the very limited imagery available of Mk14 EBR-pattern rifles in Ukraine it appears that numerous clone builds have been assembled in-country and that the only EBRs which can be identified as potential US transfers are the two Mk14 Mod 1 variants seen so far.

If the US was to transfer a significant number of Mk14-pattern rifles I would expect them to be the Mk14 EBR-RI, the most common variant, some 6,000 of which were assembled by Rock Island Armory – TACOM [Tank-automotive and Armaments Command]. It is unsurprising clone rifles have been assembled by combatants in Ukraine as Sage International and a number of other US manufacturers offer EBR-pattern chassis which do offer some improvements over the traditional M14 configuration.

M14s in Ukraine

Over the past month or so we’ve seen an increasing number of photographs of M14 rifles appearing in Ukraine. Developed in the 1950s and chambered in the brand new 7.62x51mm cartridge it entered US service in early 1960. They’ve since seen service around the world, most recently in Ukraine.

While the US Department of Defense has confirmed the transfer of 7,000 assorted small arms so far, these rifles are largely thought to have originated from the Baltic states of Latvia, Lithuania and Estonia who have been extremely supportive of Ukraine since the weeks preceding the Russian invasion in February. We can’t be certain from which country or countries the rifles originated from. The Baltic states received large numbers of the rifles from the US via Security Assistance packages when they began to work towards compliant with NATO standards in the 1990s. The transfers were reportedly made under the Excess Defense Articles program. All three of the countries eventually joined NATO in March 2004.

*Latvian marksmen with upgraded M14s (Latvian Armed Forces)*

Latvia received its first batch of 10,000 M14s in 1996 with a larger second back of 30,500 arriving in 1999. Latvia’s National Guard continues to use M14s in a designated marksman role with an interesting new railed forend for optics and accessory mounting. No M14s in this configuration have been seen in Ukraine.

Lithuania reportedly received 40,000 from the US in the late 1990s and continues to retain the rifle in its inventory, updating substantial numbers to their M14 L1 spec, with scopes. Other elements of the Lithuanian Armed forces also use the MK14 EBR. In 2019 it was reported that the US had transferred a further 400 rifles fitted with scopes and bipods. The M14 is also in use with the Lithuanian National Defence Volunteer Forces.

*Lithuanian troops with M14s c.2012 (Lithuanian Armed Forces)*

Estonia also received a considerable number of the rifles in the 1990s, with estimates suggesting that 40,500 were transferred in 1998. Estonia is in the process of a major small arms modernisation programme and may have transferred surplus rifles to Ukraine. Estonian troops used scoped M14s in Afghanistan and at least two accurised versions of the rifle have been developed, the M14 TP in 2000 and the M14 TP2 in 2008. The M14 TP2 utilises a Knight’s Armament RAS- 14 rail mount and a Schmidt and Bender, Inc. 3-12×50 mil dot reticle day scope.

The M14s seen in Ukraine have some variation. There has been a mix of both wooden stocked and fibreglass stocked rifles, some have been fitted with optics, others have only standard iron sights. The first sightings of M14s came in mid March with both wooden and fibreglass stocked rifles seen. The rifles first began to appear in mid-March.

*Ukrainian Territorial Defence Force personnel training, June 2022 (Ukrainian MoD)*

Then in April another photo of an M14 with a wooden stock and iron sights emerged, reportedly in the hands of an international volunteer. In May, several more photographs surfaced with Territorial Defence Force troops seen with fibreglass stocked rifles. A short video which appears to show a standard M14 in the field also appeared via TikTok while the first video demonstrating disassembly of the rifle also surfaced towards the end of the month.

June saw a number of photographs of the rifles shared on line. On the 31st May, the 121 Kirovohrad Territorial Defense Brigade, shared photos taken during training showing M14s with wooden stocks and iron sights. As well as a photograph from a Czech photographer showing a fibreglass stocked M14 with an optic, at the base of an International Volunteer unit operating near Donetsk.

On June 3 the Armed Forces of Ukraine social media shared a series of photographs heavily featuring a member of the southern department of the Territorial Defence Force with a scoped, wooden stocked M14.

*A member of the 121st TDF Brigade with an M14 (Ukrainian MoD)*

So far we haven’t had any clear photographs of rifle markings and we don’t yet know just how many M14s have been transferred to Ukraine. The TDF training photographs shared by the Ukrainian Ministry of Defence at the start of June give us some indication of how some of the rifles might be issued and used. We see that in a squad two scoped M14s have been issued alongside an RPK-pattern light machine gun and some AK-74s. The nature of issue for the non-scoped rifles is still unclear.

Winchester Select-Fire Garand Prototype

The Cody Firearms Museum, at the Buffalo Bill Centre of the West, holds a number of interesting select-fire M1 Garand rifles, adapted by Winchester during the 1940s. In this article we’re going to examine one of the prototypes, the rifle is believed to date to the late 1940s, and appears to be chambered in one of the earlier iterations of the T65 .30 Light Rifle round, which would eventually be adopted as 7.62x51mm.

Very little information is available about the rifle and little has been written about it previously. It is believed to have been developed by Winchester engineer Harry H. Sefried II with former Cody Firearms Museum curator Herbert Houze crediting Sefried with the rifle, which he described as adaptation of the M1 into a ‘squad automatic rifle’. After some archival research and combing Winchester’s patents from the period we can now attempt to shed light on a little more of the rifle’s history.

Externally, the rifle has a number of instantly recognisable distinctions from the standard M1 Garand. It has a reshaped stock with an added pistol grip, a proprietary box magazine and a combined bipod and conical flash hider. If we look closer we’ll notice that the stock has a swell just ahead of the breech, flaring out in an almost triangular bulge. These changes to the stock also distinguish this rifle from Winchester’s other select-fire M1 adaptations, which retain the standard Garand stock profile.

From the patents available combined with an examination of the rifle we can learn a lot. We cannot rely on patents to tell the whole story of the rifle, however, as many of the elements that make up the weapon appear to have gone unpatented. The substantial external and internal changes made to the rifle suggest that this was not an attempt to adapt the M1 with a minimal number of component parts changes but rather an effort to generally improve the rifle, making it conducive to fully automatic fire.

In summer 1944, Winchester’s CEO Edwin Pugsley directed Sefried to begin work on a select-fire conversion for the M1, to rival those being developed at Springfield Armory and Remington. Winchester’s select-fire Garand went though a number of iterations which resulted in two patents from Sefried. The first, filed in August 1944 (US #2479419), incorporated an elongated sear actuating lever and a selector on the lower, right side of the receiver. Winchester’s first attempts at a select-fire M1 conversion resulted in rifles with extremely high, uncontrollable rates of fire of over 900 rounds per minute. Sefried filed a second patent later in January 1948 (US #2464418) which used a catch to hook the sear. The rifle we are examining appears to have yet another select-fire system, one for which I have so far been unable to find a corresponding patent for. Winchester’s work on the select-fire adaptation came to a halt with the end of the war. It appears, however, that Winchester again began to work on adapting the M1 in the late 1940s, with Sefried again working on the project, filing his second select-fire mechanism patent in 1948 (US #2464418).

The rifle’s receiver was originally a standard Winchester-made .30-06 M1 with a serial number of 1,627,456. This means its wartime production gun, dating from May 1945. It would appear that rather than the rifle being lifted from the rack finished, it seems that it was earmarked for prototype development because the receiver forging lacks the cuts/forgings needed for the en bloc clip release lever. This makes sense if it was known that the receiver was destined for use in a prototype which fed from a box magazine. However, the timeline of the rifle gets more complex when we consider that it was a late-war production rifle. There are a number of possibilities. The rifle may have been simply set aside for internal prototype work in May 1945 and not used until a T65 chambered rifle was developed later. Alternatively, it is possible that the rifle was converted during the initial attempts to create a select-fire M1 but was later rechambered from .30-06 to the new developmental T65 round.

This prototype’s trigger guard assembly, which also comprises the magazine well floorplate, is a self-contained assembly and does not interact with the weapon’s trigger mechanism or action. While Sefried had a patent for his own magazine system (US #2386722) this rifle uses a slightly different magazine release and floorplate, which is similar to one seen in Stefan Janson’s 1956 patent for a stripper clip-loading box magazine for the M1 (US #2894350). The magazine used in this prototype, however, is not the same as Janson’s. It has fixed feed-lips and a projection at its rear which appears to house an anti-tilt tab for the follower.

The rifle does not to appear to use the full-automatic system seen in either of Sefried’s patents. Similarly, the safety selector is located on the left side of the receiver, forward, in line with the breech. It has two positions with an arc of about 90 degrees. This position does not match Sefried’s patents for select-fire conversion, however, it does match the position patented by David Marshall Williams but not Williams’ selector’s orientation of travel. I have been unable to find a patent which matches this rifle’s selector or method fully-automatic conversion.

The pistol grip is an interesting addition as neither of the other Winchester select-fire prototypes nor the original select-fire Springfield prototypes incorporated one. Visually it is very similar to that seen on the later Italian Beretta BM 59 Mark II. In an effort to lighten the rifle the prototype also has an aluminium buttplate. One of ingenious internal changes is the milling of the bottom of the barrel flat, this not only has the effect of lightening the rifle but also allows a new, straight operating rod to travel rearwards under the barrel. How this impacted on the barrel’s harmonics is unclear. The rifle certainly feels lighter and handier (when unloaded) than you would expect, weight is estimated to be around 7 or 8 lbs.

The bipod, patented by Sefried in April 1945, (US #2420267) comprises a pair of tube steel legs, which have a set height, and a conical aluminium flash hider. The legs are spring-loaded and the entire assembly attaches via a latch which seats over the rifle’s bayonet lug. The bipod is the only element of this rifle that can be attributed to Sefried directly. And by the bipod’s very nature of attachment may simply have been attached later.

Sefried's April 1945 bipod and flash hider patent (US Patent Office) — Sefried’s 1947 patent for the bipod-flash hider (US Patent Office)

The best documentary source available for the prototype is the entry in the Winchester Factory Museum’s collection inventory offers some tantalising clues but no definitive answers:

#1504 U.S. Model M-1 rifle (Garand)
Cal. 30-06; experimental semi or full auto.
3rd type 20 shot box mag.
Special butt plate for shoulder rest
Bipod and aluminum flash hider attached
From H. Sefried 10-26-45

The suggestion that the rifle is chambered in .30-06 is seemingly an error given the internal changes made to the rifle. ‘3^rd type’ suggests an iterative development of the rifle’s magazine while “special butt plate for shoulder rest” may allude to the aluminium butt plate but the prototype’s plate has nothing resembling a ‘shoulder rest’, instead it is a simple chequered aluminium plate about 5mm thick. While ‘From H. Sefried 10-26-45’ may refer to the whole rifle, I believe it more likely refers simply to his bipod.

A close up of Sefried’s bipod-flash hider (Matthew Moss)

The prototype appears to be chambered in an iteration of the .30 Light Rifle round, which later became known as the T65. The rechambering was achieved by installing a metal block which shortened the magazine well. Unlike earlier Winchester select-fire conversions this rifle feeds from a proprietary magazine designed to feed the T65 round. This magazine does not appear to closely follow the pattern used by Winchester on several other designs during the period. The projection from the rear of the magazine slides along a channel cut in the metal magazine well block. It has font and rear locking shelves, with the front shelf acted on by the magazine release lever.

Development of the .30 Light Rifle round, which would eventually become 7.62x51mm, began in 1944, with the round first being referred to as the T65 in 1946. It appears that the rifle is chambered in a version of the T65 cartridge, but which iteration exactly is unknown. However, its chambering does support the theory that the prototype may date from 1947-48. The T65 didn’t take on the now standard 7.62x51mm dimensions until 1949 in the form of the T65E3 round but without a chamber casting it is impossible to know the rifle’s exact chambering.

While Winchester continued to work on adapting the M1 Garand into a select-fire rifle none of their rifles were seriously considered by US Ordnance. At the same time John Garand was working on his own series of select-fire, magazine-fed prototypes (the T20 series) at Springfield while Remington had also been awarded a contract to develop a similar rifle, tested under the designation T22. These projects subsequently gave way to a number of other designs, all chambered in the T65 round, including the T25/47, T44 and T48. These were all tested before the Garand-influenced T44 was eventually selected in 1957, becoming the M14.

Addendum:

Harry Sefried II served in the US Army Air Corps during World War Two before joining Winchester as a firearms designer in 1944. In the 1950s he left Winchester to become Ruger’s chief engineer until he retired in 1979. He died in 2005, aged 84.
