This Knights Armament Company SR-15 Mod 1 complete upper receiver will make you feel like a tier 1 operator. This latest evolution comes with the improved URX 3.1 with a longer overall length to allow for better muzzle stabilization. This alteration allows for reduced weight by removing the commonly unused rail section of the system. This provides you with a thinner rail diameter that is easier on the hands, while still providing you with the modularity to add important rails.
