Wilson Combat WC10 Lower Parts Kit

Finish out your Wilson Combat WC10 lower receiver with the WC10 Lower Parts Kit. Including quality machined parts, this parts kit will provide everything needed on the lower receiver other than the fire control group and pistol grip. This allows the user to choose the trigger and pistol grip that they prefer.

This Lower Parts Kit is a step above the rest by featuring upgraded parts such as the Buller Proof Bolt Release, improved takedown pins, and many more springs and detents. Since 1977 Wilson Combat has been the leading innovator in high-performance, custom 1911 handguns, tactical long guns, and accessories.

Build a quality firearm that will last you a lifetime with Wilson Combat’s precise engineering.

Note: This Lower Parts Kit only works with the Wilson Combat WC10 and no other AR10 or SR25 lower receivers.
