LMT Defense Ships Initial Delivery to USSOCOM MRGG-S Down-Select Trials

Eldridge, Iowa – Aug, 10th 2022– LMT Defense (formerly known as Lewis Machine & Tool) is excited to announce that we have qualified for down selection and have delivered the initial units for user evaluation to USSOCOM

Starting in 2019 USSOCOM (United States Special Operations Command) voiced its desire to field a weapon system that could provide overmatch on the battlefield against small arms threats. The initial caliber choices for such and endeavor were the 260 Rem and 6.5 Creedmoor. The 6.5 Creedmoor was ultimately chosen due to ability to engage targets at significantly longer distances than the 308 Win or 7.62 NATO and unmatched commercial ability to acquire or produce cartridges from available components. This move follows a common thread in modern US warfighting to improve soldier lethality in combat.

The MRGG-S or Mid-Range Gas Gun (Sniper) program was developed and solicited to the defense industry. Specifics for the weapon system were delivered and would primarily benefit NSW (Naval Special Warfare). The MRGG-S would feature a 20” barrel, fully adjustable stock, meet 1 MOA accuracy at 100 yards, quick change barrel system, and feature a sound suppression system all while working under tight length and weight constraints. LMT Defense using successes in DMR programs starting as early as 2009 with the L129A1 delivered to the UK MOD (United Kingdom Ministry of Defence), was able to meet the needs of SOCOM quickly and efficiently with commonly utilized components.

LMT built a MARS-H weapon system with a few specifications to better meet the needs of Americas premiere war fighters. Our tried-and-true MRP-H monolithic upper was lengthened slightly to accommodate users with clip-on night vision or thermal devices as well as laser aiming equipment. Additionally, the locking screws for the MRP were designed to be captured thus increasing reliability in field operations where barrel swaps would be required. Weight savings were seen not only in the upper, but the 6.5CM barrel that was also specifically enhanced to best perform with the ammunition chosen by the end user. For the first time on a MARS-H or MWS, we see the addition of a forward assist. This was requested by NSW to improve the reliability of seating a round in battery when utilizing the weapon in low light conditions where “press checks” are commonly employed. To top it off, a custom titanium suppressor fitted to a Keymo flash hider and a fully equipped accessory case is provided with the weapon.

Summer of 2022 marked our final accuracy qualification of the initial delivery of MRGG-S program rifles. The average MOA achieved out of this delivery was just under .85 MOA collectively. The weapon systems now enter a user evaluation phase where the performance, handling ergonomics, and characteristics of the weapons will be field tested to meet the demands of the end user. We are thoroughly pleased with the product made in part by the unwavering effort of our staff here in Eldridge, IA and look forward to the results of the MRGG program as a whole.
