LMT L129A2 as adopted by the UK Royal Marines

The U.K. might be considered the Old World by us Americans, but the U.K. Royal Marines are on the absolute cutting edge with their newest DMR. Specifically, the Royal Marines have adopted an LMT AR-10-type rifle in 6.5 Creedmoor with HUXWRX suppressors and the Leupold Mk5 HD – a wonderful combo.
The Royal Marines, along with the British Army’s Rangers, also recently selected the KAC KS-1 as the L403A1 Alternative Individual Weapon.

LMT @ TFB:

Full details in the LMT press release below:

In 2009, LMT was pleased to establish a contract with the UK Ministry of Defence for the adoption of a new designated marksman rifle that would become the L129A1. This weapon was developed to field a solution for a long-range rifle that could also offer fire support in close range engagements. The L129A1 has been deployed to countless combat theaters around the globe and was eventually upgraded by the UK Royal Marines to an SSW or Sniper Support Weapon with a new sighting system.

After more than a decade of service, the UK MoD needed to update the L129A1 to a more modern, combat effective configuration. LMT, while working with LEI (Law Enforcement International) and the UK Royal Marines, revamped the L129A1 configuration to meet the demands of today’s battlefield and utilize improvements in weapon system capability. The current configuration of the L129A2 has changed in every characteristic aside from the fact it remains a direct impingement Monolithic Upper Platform rifle.

Starting at the heart of the weapon, the classic MWS lower receiver has been updated to the fully ambidextrous MARS-H system. This lower also brings the new AXLE two-stage trigger and fully adjustable DMR stock in addition to the mirrored controls. The monolithic upper remains backwards compatible with the L129A1, however features the warfighter preferred MLOK rail configuration for improved ergonomics and accessory mounting. This new rail is extended significantly to increase the platform for mounting thermal and night vision optics as well as laser aiming devices. Probably the most notable change over its predecessor is the L129A2’s new caliber. Now featuring an 18” 6.5CM for increased ballistic performance, the A2 gives the Marines a modern performance cartridge while still remaining mission adaptable and able to accept the A1’s 7.62X51mm 16” barrel with the quick-change barrel capability.

To round out the L129A2, the weapon has received a full FDE treatment with a Cerakote finish to match its furniture. A2 is also equipped with an improved accessory package for the new rifle and will include a HuxWrx Helix suppressor, Leupold MK5 HD rifle scope, and a Pixels on Target thermal sight.

    It took the UK sixty years to adopt a sixty year old design and call it cutting edge.

    Next up: a brand new idea! Iron-covered wooden ships powered by STEAM!!!

      @Brettbaker Ok, so I listened to Primers 38, 39, and 40 today, and it sounds like all of those guns were bored larger than .30, with one or two exceptions. Those were being looked at in 1914, but forgotten when the war kicked off, so never adopted. 7x57, which reminds me of another wonderful, and well aged cartridge under .30 from that period. I think it got adopted by a couple Spanish-speaking nations, and was used in the Spanish-American war.

    Could have saved a lot by just getting new barrels and lowers.

      @Lee Agreed, good on LMT. They deserve it. Just weird to buy a platform with the big selling point of being able to quickly change the barrel after it's worn out or you need a new caliber only to get a whole new system...in a new caliber.
