Wilson Combat Receiver Set, Lower/Upper Matched Set, Billet, AR15/M16, Lightweight, Black Armor-Tuff®

Designed by Bill Wilson and the Wilson Combat design team to be the base for the ultimate precision tactical AR-15 rifle, the BILLet-AR matched upper and lower receiver set is 100% machined in our Berryville, AR facility.

The Wilson Combat BILLet-AR receiver set was engineered from the ground up to address structural design weaknesses in standard USGI receivers and enhance overall tolerances which improve shot to shot consistency.

The BILLet-AR upper receiver has a precise bolt raceway for smoother chambering and more rigid receiver walls to reduce firing flex. The BILLet-AR lower receiver has been enhanced with an oversize magazine well for smooth reloads and an integral trigger guard for gloved use and added lower receiver strength.

Our extensive experience as a premier custom builder of AR-15 rifles will ensure your satisfaction with this next generation precision tactical shooting platform.
