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 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. This receiver has been lightened for the lowest weight possible. Compatible with all Mil-Spec AR-pattern lower receivers.
Our extensive experience as a premier custom builder of AR-15 rifles will ensure your satisfaction with this next generation precision tactical shooting platform.

Quality Light Weight Upper | 12/1/2022 |
High quality upper receiver. Precision, Smooth operating and conducive to better accuracy. There's a reason Wilson Combat uses it on their weapons. I built a 6 ARC on it and it's a tack driver. | ||
