0-10 Scale Across 8 Axes
The Geissele MRGG-S MK1 Mod 0 is a limited-availability 6.5 Creedmoor precision gas gun tied to Geissele's SOCOM MRGG-S contract. Public reporting confirms the 2023 SOCOM award; civilian availability is intermittent, so contract and enthusiast-spec details should be confirmed against the exact rifle on offer.
The MRGG MK1 replaced or supplemented the aging SR-25 and M110 DMR platforms in SOCOM armories, bringing 6.5 Creedmoor's wind resistance and supersonic reach to teams that needed sniper-class precision without bolt-action handling penalties. The rifle ships with the Geissele SSA-E two-stage trigger, fully ambidextrous controls, and Geissele's 17.5-inch MRGG MK18 handguard. Weight lands at roughly 10.8 lbs, and overall length is about 41.5 inches collapsed.
For civilian buyers, this is a reference-tier 6.5 CM precision gas gun. It belongs at the top of the price ladder and should be paired with premium glass and match ammunition.
