CMMG Resolute Mk4 6mm ARC 16.1"

The CMMG Resolute Mk4 in 6mm ARC is the answer for coyote hunters who keep getting busted on the long shots a 5.56 carbine cannot make. 6mm ARC was designed to fit the AR-15 magazine well while launching high-BC 6mm bullets at velocities that stay supersonic past 1,000 yards, and on coyotes that translates to flat trajectories and authoritative terminal performance from 300 to 500 yards where 5.56 starts to fade.

The 16.1-inch 416 stainless barrel runs a 1:7.5 twist that stabilizes the heavy 105- to 108-grain match and hunting bullets the cartridge was built around, and the 5/8x24 muzzle threads take the same .30-caliber suppressors a deer or 6.5 Creedmoor rifle uses. Rifle-length gas keeps the action smooth, and CMMG's ZEROED drop-in trigger, EML15 M-LOK handguard, and ambidextrous controls make this a turnkey predator rig rather than a parts bin.

6mm ARC shares the 6.5 Grendel case head, so it feeds from Grendel-pattern magazines and bolts. Budget for a couple of quality Grendel/ARC magazines and confirm your factory loads cycle before opening day. At $1,599.95 MSRP it costs more than a budget 5.56, but no 5.56 carbine matches its reach on fur.
