Key Features and Tactical Benefits

6mm ARC Ballistics

The 6mm ARC was designed to give AR-15 platforms ballistic performance closer to larger AR-10 cartridges while maintaining controllable recoil and lighter ammo weight. Expect flatter trajectories and more retained velocity at extended ranges compared with typical 5.56 options—ideal for precision work from 300–800 yards when paired with the right optics and fundamentals.

Chassis and Controls

The medium-taper Black Nitride 16.10″ threaded barrel balances heat dissipation and maneuverability. The EML handguard’s full M-LOK layout supports modern accessory placement and sling mounting. ZEROED factory components reduce time at the range: the drop-in trigger improves trigger feel immediately, and the ambidextrous controls make the rifle adaptable to left- or right-handed shooters.
