BRN-180M LOWER RECEIVER FOR SALE
The Guns Buyer USA BRN-180M Lower Receiver is specifically designed to pair up with the BRN-180 Upper Receivers to maximize the full potential of this unique line.
While designed to be fully compatible with Mil-Spec lower receiver parts and triggers the BRN-180M Lower Receiver does away with the traditional receiver extension threads and in their place has a milled in 1913 Picatinny rail section for mounting of stocks or braces such as the line for the Sig Sauer® MCX.

This Lower Receiver is made from billet 7075 T-6 aluminum with a hard-anodized finish, has integral oversized trigger guard, and the unique features of a threaded bolt catch pin and captive set screw for the takedown pin detent spring, both included.
Due to the proprietary design nature of the BRN-180M Lower Receiver it will not function with standard AR-15 upper receivers.

GREAT COMPANION LOWER TO BRN-180 UPPER!
Bought this after I ran my BRN-180 upper on a standard AR-15 lower receiver. While the AR-15 lower was fine, I wanted this lower for the folding stock capability and to match the BRN-180 upper. This lower is well crafted and a perfect complement to your BRN-180 upper. It’s tough and accepts AR-15 LPKs. If you run a BRN-180 upper on a standard AR-15 lower, consider switching it to this lower.

READ THIS AND SAVE SOME TIME
I read the other reviews here, and I’ll add my 2¢. This is clearly not a traditional AR-180 receiver, so if you want a look-alike go elswhere. If you want a rifle that works, this lower will do very well. Several of the other reviews indicated fit and finish issues. I had none. Everything fit perfectly, and I really like the threaded pin for the bolt hold-open. As for the take-down pin detent spring set screw, you don’t need it, so throw it away. That has the effect of shortening the spring, as others have indicated needing to do, and making installation a lot easier, because you won’t waste time looking for the screw after it inevitably goes flying across the room. Just let the pistol grip hold it in place like the buttstock does on an AR-15 lower. You’re already doing that with the safety detent spring, anyway.
