Geissele MRGG-S MK1 Mod 0 6.5 Creedmoor 20"

The Geissele MRGG-S MK1 Mod 0 row is a limited/reference 6.5 Creedmoor precision-gas-gun entry tied to Geissele's SOCOM MRGG-S contract reporting. Public reporting confirms the 2023 SOCOM award, but a live Geissele firearm product/spec page was not found during this audit, so this row should avoid presenting every contract or enthusiast-spec detail as a current retail SKU.

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, but deal tracking should wait for a direct Geissele product SKU before treating this as a normal retail row.
