The Wilson Combat Billet upper receiver was designed by Bill Wilson and engineered to deal with the structural short-comings of USGI receivers, at a tighter tolerance for maximum accuracy potential. The precision machined, undersized bolt raceway enhances the action by better supporting the bolt carrier. Each receiver is hand prepped at Wilson Combat's facility in Berryville, Arkansas, to ensure a perfect finished product.
