MRGG 6.5 Creedmoor 16" Bbl Black Rifle 08-528B traces its lineage straight back to a SOCOM program — this is the civilian version of the Geissele MK1 MOD0, adopted and battle-proven as part of the Very Long-Range Semi-Automatic Sniper System requirement. This Geissele MRGG 6.5 Creedmoor 16 build runs a cold hammer forged, chrome-lined CRMOV barrel with a 1:7.5 twist, cut for 6.5 Creedmoor's flat-trajectory ballistics without the added length of the full 20" platform. Geissele's Phased Array® gas system with Tri-Port™ metering runs through a custom rifle-length gas system, keeping recoil impulse and follow-up shot timing consistent even as the barrel heats up. Billet upper and lower receivers, Type III hardcoat anodized, give the platform the rigidity match-grade accuracy actually depends on. The Geissele 6.5 Creedmoor platform's MK18 rail runs 13.5" with an integrated ARCA-Lok bottom rail, useful for bipod and tripod mounting on precision setups. Inside, the Nanoweapon®-coated Reliability Enhanced BCG runs a forged Carpenter 158+ bolt, and the SSA-E two-stage trigger delivers a clean, repeatable break. A braided-wire Super 42 buffer spring cuts recoil further, and a Magpul PRS Lite stock, flared magwell, and oversized trigger guard round out the ergonomics.
