AR-15 80% Polymer Lower Receiver With Jig

AR-15 80% Polymer Lower Receiver With Jig Features

This Polymer80 80% AR-15 lower receiver kit includes everything you need to finish the build at home: the polymer receiver blank, the jig, drill bits, and the end mill required to complete the machining. Molded from polymer rather than aluminum, it’s noticeably lighter than a standard billet or forged 80% lower, and it’s compatible with a range of calibers, including .223/5.56, 300 AAC Blackout, 9mm, 7.62×39, 6.5 Grendel, and .45 ACP.
