Mark 4: Patrol


SKU: N/A Categories: ,


Chambered in 6.5 Grendel with a 10.5-inch Bear Creek Arsenal parkerized heavy barrel, with a 1:8 twist and a pistol-length gas system. We suggest using Hornady Black 123 grain ELD for hunting or self-defense situations. This is our flagship upper that we suggest for multiple uses such as hunting, home defense, or mission and destination unknown situations. This basically can replace the ballistics of a 5.56 but with a shorter PDW-like package.
