Aero Precision EPC-9 Assembled Upper Receiver

The Aero Precision® EPC-9 Assembled Upper Receiver accepts most AR-15 compatible barrel nuts and handguards and features a last-round bolt hold open mechanism. This upper receiver is machined from anodized 7075-T6 aluminum and utilizes a standard AR-15 takedown/pivot pin lug pattern. A dimple above the receiver threads gives a visual reference for proper handguard timing when needed. Laser-engraved T-Marks on the top Picatinny rail make mounting your favorite optics easier than ever. Comes with pre-installed last-round bolt hold open assembly. Made in USA.
