Chambered in .223 Wylde with a 16-inch Rosco Manufacturing Purebred stainless-steel barrel with a 1:8 twist and a mid-length gas system. Choose the .223 Wylde option for maximum accuracy. We recommend the Rifleman to anyone who prefers to use hunting or personal defense ammo. The Rifleman is capable of shooting both .223 Winchester and 5.56 very accurately, it is the fusion of both into one. This is the suggested barrel for the Mark 1.

MARK 1 - RIFLEMAN
Mark 1: BLUE SPADER
Chambered in 5.56 with a 16-inch Rosco Manufacturing Bloodline black nitride barrel with a 1:7 twist and a mid-length gas system. This is tailored for people who like to shoot mil-spec ammo. The platform is still capable of great accuracy of both .223 Winchester and 5.56 but for hunting purposes we suggest using the .223 Wylde to maximize your accuracy even more. The Blue Spader favors heavier mil-spec projectiles. We suggest using 5.56 M855 green tip ammo.
