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 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, an oversize magazine well for quick reloads and an integrated 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.
The BILLet-AR is only available from Wilson Combat as a custom upgrade to existing AR-pattern rifle models and on complete upper assemblies.
