The CMMG Endeavor Mk3 in 6.5 Creedmoor (brand part no. 65A780C-AB) is a semi-auto direct-impingement rifle built on CMMG’s larger Mk3 platform, an LR-308/DPMS Gen 1 high-pattern receiver sized to handle bigger calibers like 6.5 Creedmoor. CMMG pairs a 20-inch, 416 stainless steel barrel with a CMMG Zeroed muzzle brake threaded 5/8×24, and builds the upper and lower receivers from billet 7075-T6 aluminum. The rifle includes the EML 15 M-LOK handguard, a CMMG Zeroed ambidextrous charging handle, and a Magpul MOE rifle stock, and ships with a 20-round Magpul PMAG. Among long-range AR-platform rifles in the AR rifles category, the Endeavor favors marksmen who want 6.5 Creedmoor’s flat trajectory and lower recoil in a purpose-built long-range rig.
