Wilson Combat BILLet-AR

Wilson Combat has released its BILLet-AR custom option for the Wilson Combat line of AR-15 rifles and complete upper receivers. This option allows customers to upgrade to a matched billet upper and lower receiver for rifle and a billet upper for complete upper receiver orders.

The BILLet-AR was developed by Bill Wilson and the Wilson Combat design team to address structural design weaknesses they saw in standard USGI receivers. The receiver walls are more rigid to reduce firing flex. While the upper receiver bolt raceway is designed for smoother chambering, and the lower receiver magazine well is oversized to help reduce reload times.
