The Wilson Combat BILLet matched receiver Sets (UB) are among the best of the premium receivers on the market. Both receivers are machined out of solid 7075-T6 billet stock with extremely tight tolerances to ensure a precise fit between the receivers. A tight, rattle-free fit is needed for the utmost accuracy, and Wilson Combat delivers. A small, rubber insert is included to apply a small amount of tension on the upper/lower receiver for a tight fit. The upper receiver has a very precise bolt carrier raceway for smoother, more consistent cycling and high reliability. The upper receiver also sports M4 feed ramps, shell deflector, no forward assist and a picatinny top rail. The lower receiver has an integrated winter trigger guard, hex bolt catch screw retention, oversized & EDM cut magwell, safety markings on both sides, rounded magwell front and the take down detent is installed through the underside of the grip (making maintenance much easier). The BILLet AR matched receiver sets are extremely strong, precise and have a classy & smooth look. Every BILLet AR set is hand prepped for a flawless finish. The quality of this receiver set is unsurpassed by any other set. The addition of the exclusive Urban Bronze cerakote yields a slicker finish that lasts through years of use, while looking great. The Urban Bronze is a dark bronze with hints of brown and OD Green.
