Cmmg Dissent Mk3 6.5Creed 20 Armor Black

The CMMG Dissent Mk3 6.5 Creedmoor is a modern long-range rifle built on CMMG's proven Mk3 platform and chambered for one of today's most capable precision cartridges. If you're stepping up from intermediate calibers to serious distance shooting—whether for hunting, competition, or the range—the 6.5 Creedmoor delivers flat trajectory and reduced recoil compared to heavier magnum rounds, making it easier to shoot accurately at extended ranges without the shoulder punishment. This isn't a budget build; it's a purpose-built long-range tool with quality components throughout.

The heart of this rifle is a 20-inch stainless steel barrel with nitride finish and 1:8 twist, optimized for the 6.5 Creedmoor's ballistic performance. The Mk3 platform uses AR10-sized (LR-308/DPMS Gen 1 high-pattern) receivers machined from 7075 T6 aluminum, paired with a compact direct-impingement gas system and adjustable gas block for tuning reliability with various loads and suppressors. The side-folding stock and reversible side-charging handle make this rifle remarkably compact when folded—down to 32.1 inches—without sacrificing a full-size shooting platform when extended. At 8.8 pounds, it's manageable for field work while remaining stable enough for precision shooting.

Features include a CMMG ZEROED single-stage trigger, 60/90-degree ambidextrous safety, integrated trigger guard, and CMMG's proprietary 15-inch handguard in Cerakote Armor Black finish. The muzzle is topped with a CMMG ZEROED brake (5/8x24 thread) that helps control recoil and supports suppressor mounting. Two Magpul 20-round LR/SR PMag magazines are included, so you're ready to load up and head to the range or field.
