Wilson Combat TRUPPERBIL Billet AR-15 Upper 5.56x45mm NATO 7075-T6 Aluminum Black Anodized

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 upper receiver set is 100% machined in our Berryville, AR facility.

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

The BILLet-AR upper receiver  has a precise bolt raceway for smoother chambering, more rigid receiver walls to reduce firing flex. 

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