What is the BROWNELLS - BRN-180M Billet Stripped Lower Receiver, Ambidextrous, Black?

BRN-180M STRIPPED LOWER RECEIVER BLACK AMBIDEXTROUS


The Brownells 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.


The new BRN-180M is now fully ambidextrous and includes ambidextrous bolt release and an ambidextrous magazine release. The ambidextrous magazine lever was designed to work in conjunction with the standard Mil-spec magazine catch for proper function. The new BRN-180M includes the ambidextrous bolt release and magazine release lever hardware.


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 Sig Sauer® MCX style stocks.


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.

Bolt catch screw, ambi-magazine release lever screw and ambi-bolt catch lever screw are all installed/removed with 1/16" allen. Take down detent capture screw = 0.050" allen. There is a tensioning screw to put pressure on the take down pin upper receiver lug = 1/8" allen

It's Not Really Ambi
Seems like good quality. My biggest complaint is that Brownell's went to all the trouble of designing an 'ambi' lower and then failed to make it with a right side bolt catch/lock!?! I prefer the design of your trigger guard to the ADM but bought theirs as well to get a truly ambi lower. I also bought a Redi-Mag Redi-Catch to use with the BRN-180M lower, so at least in the event of a double feed, it will be easier to manage. All that said, I'm still waiting on some LPK parts and waiting on Brownell's to sell a .223 Wylde 10.5-12.5" upper (and a 13.9" with non P&W bbl to go with the ADM lower) before I assemble this lower. The left side mag release seems like it should work well, but obviously, I can't say until I actually put it all together.
Would you recommend this? Yes, I would recommend to a friend

Disappointing thus far
Looked good and sounded good. Came with about 7 or 8, admittedly very minor, but none the less nicks on top of the inside of the receiver. In no way should this effect functionality but is dissapointing when buying a brand new product at the higher end of the price scale! As to functionality - WOULDN'T KNOW - because the lower uses a screw style pin vs. a reg roll pin for the Bolt Catch/Release which, as per product description should be included/installed on the lower, and IT WASN'T! To make matters worse Brownells doesn't have the screw pin in stock and back order might be filled at the end of Jan, which is about 6 weeks away. Will be hunting screw pin now. Further, the Bolt Catch function is not trully Ambi. You cannot catch the bolt from the right side - only release it. Which wouldn't be much of an issue really except that on the Gen 3 Upper the charging handle is on the left now! Defeats the whole darn purpose of an Ambi lower and moving charging handle to the left because there is no way to efficiently lock the bolt back. Makes the set up real combat ineffective because you have to do an AK reach around and in essence let go of the rifle to lock back the bolt and take rifle out of ready position. Not the end of the world but is goofy and awkward considering the entire design. Have to look for a real ambi solution for the Bolt Catch/Release now!

Missing critical part
The receiver is beautiful. Unfortunately the bolt catch takes a screw rather than a roll pin, and it was not in the box! Makes the receiver unusable until I can get one. How long will that take?
