LMT MWS MRGG-A Reference Rifle 6.5 Creedmoor 14.5" SBR

The LMT MWS MRGG-A Reference Rifle is a limited/reference civilian SBR associated with the carbine LMT Defense is delivering to SOCOM under the MRGG-A (Mid-Range Gas Gun, Assault) contract, awarded in August 2025 with a $92M ceiling over 10 years. Public LMT contract material confirms the award; civilian retail references identify a 14.5-inch 6.5 Creedmoor factory SBR SKU. Because the civilian reference keeps the short barrel, it transfers as a factory SBR on a Form 4.

The MRGG-A (Mid-Range Gas Gun, Assault) is the carbine/assault track of SOCOM's MRGG program, distinct from the separate MRGG-S sniper/DMR track. It is a lighter, shorter 6.5 Creedmoor system that retains DMR-class reach with carbine handling. The 14.5-inch barrel gives up roughly 200 fps versus a 20-inch MRGG-S but keeps the rifle viable in vehicle and CQB-adjacent roles while still delivering 6.5 CM ballistic advantages past 600 yards.

For civilian buyers, this is a reference rifle first. At roughly $5,200 in the 14.5-inch SBR configuration, it is for shooters who specifically want the short LMT MRGG-A-associated configuration, and the short barrel pairs naturally with a suppressor in a DMR or defensive role. Buyers who do not want an SBR should pick the 20-inch LMT MWS/MARS-H or another 20-inch 6.5 CM gas gun instead.
