Greg Felton of Law Enforcement International (LEI) in the UK, was trying to meet the requirements of a friendly Government to supply a 7.62x51mm “Designated Marksman Rifle.” No product on the market met the client’s particular specifications. Greg brought in Karl Lewis of Lewis Machine & Tool (LMT) from the U.S. After much brainstorming about the needs to be filled by this new rifle, Karl and Greg started in on the project. The client wanted select-fire capability, but the first designs were kept to semiautomatic only, with a 16-inch barrel. By good fortune, as final development and trials on the semiautomatic were completed, the British MOD published an “Urgent Operational Requirement” (UOR) solicitation for such a rifle for immediate deployment in Afghanistan. The rifle was submitted for trials and the design won the competition, was contracted for and designated as the L129A1 rifle, with the vernacular name as the “Sharpshooter Rifle;” comparable to the U.S. DMR (Designated Marksman Rifle). LMT and LEI have now finished development of the select-fire version, as well as some rifles with shorter (13.5-inch) barrels and other options – but that’s another story…

In essence, Lewis Machine & Tool’s semiautomatic rifle, the LM308MWS, has been selected by British MOD as the new Sharpshooter rifle. The version of this rifle was in competition with the FNH SCAR-17 (Mk17 Mod 0), the HK model 417, Sabre Defence’s XR-10 and offerings from Knights and Oberland Arms. When the competition was over, LMT’s rifle was designated as the L129A1. It has been several decades since MOD has changed rifles for the longer range duties, and the new L129A1 is geared towards the 800 meter ranges being encountered in today’s combat environment. The AI .338 bolt action replaced and upgraded the AI L96 7.62mm several years ago. “Sharpshooter” is a completely new role for the British Army. Quick reaction, rapid follow up shots, long range, harder hitting than 5.56mm is the idea for the L129A1, but the sniper rifle is still a bolt action.

Greg Felton from LEI explained the ammunition requirement to SAR:

“The ammunition criteria stated by the MOD was that the rifle was to be able to use both RG 155-grain sniper ammunition, plus M80 ball and tracer, including de-linked machine gun belts. In the end during their trials with the various competitors, they found that the 155-grain fired so much better than the standard ball that it was made the official issue ammunition for the weapon. As to what it is “matched to,” we (Karl & I) designed the rifle to use both standard ball and 168-grain Match. With a 1:11.25 inch twist it works well with these weights, however, the heavier 175-grain projectiles need a faster twist for best results at longer ranges.”

The LMT Monolithic Rail Platform is a one piece milled upper receiver that includes four rails to the front, providing a stable platform for returning devices to zero on installation. It also allows for a free floating barrel that is interchangeable for different lengths, although not in this particular issue.

The initial order of 440 L129A1 Sharpshooter rifles has been added to several times now. The L129A1 has been in combat in Afghanistan since April 2010, and has received excellent field reports from the troops.

  • British L129A1 “Sharpshooter” rifle with ACOG optic removed, showing Back-Up Iron Sights (BUIS) in ready position. LMT supplies the Tactical Adjustable Rear Sight and Tactical Front Sight on the L129A1 for BUIS.
  • British L129A1 “Sharpshooter” left hand side with bipod folded. A monopod front grip can be added to the lower rail.
  • British L129A1 “Sharpshooter” left hand side.
  • Right and left sides of L129A1 receiver sections.
  • Another positive feature of LMT’s Monolithic Rail Platform design is the relative ease with which barrels can be changed for either standard replacement, or changing barrel length used. The two torx bolts at center are loosened with the supplied torque wrench.
  • The British L129A1 “Sharpshooter” is delivered in a Pelican case with eight 20-round magazines, Otis cleaning kit, torque wrench and general user’s tools.
  • Correct L129A1 markings. Note the ambidextrous magazine release button at the rear of the magazine well and large paddle bolt release.
  • Looking at the bolt face of the L129A1 bolt, the beefed up extractor and ejector are both evident, as are the broader angles of the multi-lugs, removing the fracture point that occurs from having the angles at 90 degrees.

Trijicon’s TA648-RMR-UKS (NSN: 1005-99-305-9104) was chosen by MOD to mount on the L129A1. The 6×48 optic uses a unique bullet drop compensating reticle system similar to their TA648-MGO-308, with illuminated chevron and 200 meter increments out to 1,000 meters. This is specific to M80 ammunition and the GPMG, which is why it was chosen as it’s in service already with MOD. Mounted on top is Trijicon’s RM01 Ruggedized Miniature Reflex sight for truly fast target acquisition at closer ranges. Since the L129A1 is not just a Sharpshooter rifle and will fulfill CQB roles for the operator, this is a needed addition.
Slings used for the L129A1 are either the standard SA80 sling or the ECSH-Tan from Northeast Tactical, mounting to the LMT front sling mount and the double loop plate at the rear.
The L129A1 was issued to us with Magpul’s 7.62x51mm P-MAG 20-round magazine, but can use the Knight’s SR-25 or M110 magazines.
The Harris HBRMS bipod is a 6-9 inch extendable folding bipod that is spring loaded for fast deployment. It is mounted to the lower rail with the A.R.M.S. 17 mount and the A.R.M.S 32 adapter, allowing for floating cant (tilt). The KMW Pod-Loc tension lever on the back quickly locks the bipod so no cant is possible.

The L129A1 package ends by installing the SureFire FH762K05 7.62mm flash hider. This would allow for the use of SureFire’s FA762K suppressor on the L129A1 rifle if required, and the flash hider attaches to the barrel’s 5/8-24 muzzle threads. This is machined from heat-treated stainless steel, finished in corrosion-resistant black Melonite. No suppressor has been purchased as of yet, or is currently required. The SureFire flash hider is for flash reduction, and SureFire was chosen to continue uniformity with products used on other weapons (SA80, Minimi, GPMG etc.).
British L86A1 Light Support Weapon. This enhanced version of the SA80/L85 British Service Rifle in 5.56x45mm was supposed to be filling the role of “Automatic Rifleman” like the 1918A2 BAR or MKII Bren, but due to caliber issues it never really met the need. Instead, with its 24-inch barrel, British troops saw it as an improvised sharpshooter rifle, a use it is not particularly well suited to.
