17 Design Billet 17DM-180 Lower Receiver AR-15 5.56 NATO

The 17 Design & Manufacturing Billet 17DM-180 Stripped Lower Receiver is the perfect base for your Brownells BRN-180 build. Their new BRN-180 lower was designed to work with the Brownells BRN-180 upper and work with standard AR15 components and ensure the highest quality and parts interchangeability.

At the rear of the 17 Design & Manufacturing BRN-180™ Lower Receiver you will find a 1913 picatinny rail section in place of the unnecessary traditional AR-15 buffer tube threads. This allows for out of the box stock or pistol brace solutions such as those for the Sig MCX or MPX that give you ability to take advantage of the BRN-180™ Upper Receivers ‘fire while folded’ design."
