Knights Armament Company Upper Receiver SR-15 Carbine 14.5″ MLOK

The Ruger PC Carbine is a take-down rifle chambered in 9mm. It comes
standard with innovative features such as a custom “dead blow”
tungsten weight which shortens bolt travel and simultaneously reduces
both felt recoil and muzzle rise. It also has interchangeable
magazine wells, one which accepts Ruger SR-Series and the new Ruger
Security 9 mags, and another which accepts Glock mags. The bolt is
machined from heat treated, chrome-moly steel to ensure strength,
structural integrity and durability. Takedown is as simple as
locking the bolt back, verifying that the rifle is unloaded, pushing
a recessed lever, twisting the sub-assemblies and pulling them apart.
