Aero Precision AR10 Upper Parts Kit – DPMS Pattern AR-10

The Aero Precision AR10 Upper Parts Kit provides all the essential small parts needed to complete an AR-10 upper receiver assembly. This kit includes the forward assist, port door assembly, and ejection port cover spring, eliminating the need to source individual components. Designed for DPMS-pattern AR-10 platforms, it ensures proper fitment and function when building or repairing a .308/7.62 NATO upper.

Manufactured from mil-spec materials with a black oxide finish on steel components and anodized aluminum for the port door. All parts are drop-in with basic armorer tools—no specialized gunsmithing required. The forward assist installs with a roll pin, and the port door assembly threads into the upper receiver. Quality control standards match Aero Precision's reputation for dimensional consistency.
