My newly built Brownell's BRN-180 pistol

I have been a huge fan of the Armalite AR-180 since I bought my first one in 1977. Unfortunately they stopped production of one of the first gas piston rifles in 1994. Since then the existing AR-180's have gone way up in price, plus even though they use a very similar magazine to the AR-15, they are also very expensive and hard to find.

Brownells has reengineered the AR-180 upper into a modern rifle/pistol upper that is compatible with all AR-15 pattern lowers. They have also manufactured a lower that uses AR parts and magazines, and was designed to pay homage to the AR-180 profile.

I put mine together as a pistol with the 10.5 inch BRN-180 upper. It has so far ran awesome, and because there is no buffer tube, it folds into a very nice package. It took it to the range last week, and it has run perfectly for the first 500 rounds. So far and awesome little pistol!!

Do you have any photos of your AR-180 based pistol?

I have a small side business selling high quality AR-180 / AR-18 magazines if you know anyone looking for any. I have a running ad in Gun Broker dot com.

Love my Costa Mesa 180. Ahead of its time.

I've been giving a serious look at the BRN180 10.5 upper. The adjustable gas on there is the selling point for me.

I went to the range yesterday, the BRN-180 ran flawlessly. I put approximately 300 rounds of Russian Silver Bear zinc plated steel and some Lake City 55 gr brass through it, zero malfunctions. The accuracy is great, I was engaging a torso size target at 125 yards, hitting it at will standing off hand.

What is the difference between the BRN 180 and the Armalite AR180B. They look very similar with both of them using what is mostly an AR lower. Am I right?

Bob, you can actually use a regular AR lower with a BRN180 upper, but since it does not need the receiver extension ('buffer tube'), the dedicated BRN180 has a pic rail to attach folding stocks (and braces) directly. One version of their dedicated lower gives a 'standard' AR-type mag-well profile, the other an AR180'esque slant.

The BRN180 was developed by Brownells in conjunction with PWS as a (soft of) 'modern' 180.

Plus the BRN-180 fits any AR receiver so no proprietary parts

I know all about the proprietary rights, I have an Armalite AR10B, one of the ones made during the Clinton Ban (when I bought it). Armalite and their use of M14 magazines to circumvent the magazine ban has not been the best move especially now that they don't sell the conversion kits or any 15 or 20 round magazines. They do have 5 and 10 round ones though.

Nodak makes a lower receiver for AR180B model that uses your lower parts and it excepts AR-15 magazines.
