The Wilson Combat TRUPPERBIL is a top-notch Billet-AR upper receiver set, meticulously machined in the USA. This product was intelligently designed from scratch to tackle and improve upon the structural inadequacies found in standard Usgi receivers, simultaneously upgrading overall tolerances. One of its notable features is a meticulously calibrated bolt raceway that ensures smoother chambering. The more rigid walls of the receiver significantly decrease firing flex, enhancing your shooting experience and precision. This Billet-AR upper receiver makes use of 7075-T6 aerospace aluminum billet stock, which is CNC machined for optimal durability and quality. Incorporated into the design is a top Picatinny rail, extended M4-style feed ramps, and a smooth side profile minus the forward assist, all geared towards achieving the maximum potential for accuracy.
