9-Hole Reviews features the LMT MRGG-A (Mid-Range Gas Gun - Assaulter), a 14.5-inch 6.5 Creedmoor rifle recently selected for a SOCOM contract, by testing its practical accuracy out to 1,000 yards. Josh and Henry, successfully engage distant targets with remarkable precision, noting that the rifle's barrel length and caliber combination offers ballistic performance similar to a 16-inch or 20-inch .308 rifle, proving that shorter large-frame rifles are viable for long-range shooting. They conclude that the MRGG-A is an extremely accurate and shootable rifle.

They further discuss the rifle's significance as a modern solution for the special operations community, capable of replacing systems like the SCAR 17. The adoption of the 6.5 Creedmoor caliber allows for better predictability and reduced wind drift compared to older 7.62 NATO rounds, providing a versatile platform that can serve the roles of both an assaulter and a marksman. This standardization on the 6.5 Creedmoor, facilitated by the LMT's quick-change monolithic upper, streamlines logistics and enhances mission flexibility for special operations planners.
