APF Armory DMR 2.0 Complete Upper 22 ARC 18" 416 Stainless M-LOK 15"

The APF Armory DMR 2.0 is a complete AR-15 upper receiver assembly chambered in 22 ARC, built around an 18" 416 stainless steel barrel with a rifle-length gas system (.750 gas port diameter) operating via direct impingement. The billet upper receiver pairs with a Nickel Boron-coated bolt carrier group for enhanced corrosion resistance and smooth cycling. A 15" M-LOK free-float handguard provides a slim, rigid platform for accessories along the full length of the barrel. The muzzle is fitted with a Butcher muzzle brake to reduce felt recoil and muzzle rise during rapid fire.
