Reviews (0)

This two-piece combo provides both an AR-15 80% lower and a P80 80% frame in one package. Many hobbyists enjoy hands-on building but often debate whether to begin with an AR-15 platform or a compact-style frame. With this set, you can explore both projects using a mil-spec polymer AR-15 80% lower and the popular Polymer80 PF940C 80% frame. Jigs are sold separately and required for completion.

You can pick up the AR-15 lower jig separately, as well as a PF940C frame jig, if needed.

Material and Durability

80% lowers are commonly made from strong aluminum alloys or reinforced polymer, each offering distinct performance. Aluminum provides higher strength, stability, and long-term durability under repeated stress, while polymer offers lighter weight and corrosion resistance but may show wear sooner in demanding conditions.
