Blemished – Tromix Billet Big Bore AR-15 Upper Receiver


1 in stock


This new Tromix 7075 aluminum big bore AR-15 upper receiver has a small blemish on the underside near the forward assist pin hole.  It appears the punch used to install the roll pin, struck the underside of the receiver during pin installation.  Other than that blemish, the receiver is in new condition and completely serviceable for your big bore build.
