The LMT L129A1 Reference Rifle in 7.62×51 (.308) is LMT’s reference to the rifle contracted by the United Kingdom Ministry of Defence. LMT builds it on its patented monolithic Modular Weapon System, a one-piece aerospace aluminum upper with two side-accessed locking bolts that hold the barrel extension for a full 360 degrees and allow quick barrel changes. The upper carries 19.25 inches of uninterrupted Picatinny rail at 12 o’clock, and the lower adds an EDM-machined two-stage trigger, ambidextrous controls and a SOPMOD stock. It ships with a magazine, an owner’s manual, flip-up front and rear sights, two heavy-duty push-button swivels and three rail panels.
