I was cruising through prime and found old episodes of The Greatest American Hero.I know it's kinda goofy. In the first episode all the bad guys had ar-180s.

I've always liked the looks of the AR18/180s. I know about the development/history and manufactures. I just don't know that much about them in the real world (never shot or handle one). Not sure if they are worth having. I would appreciate any input.

I had and enjoyed one of the polymer-framed AR-180Bs, but the rate of twist really favored lighter bullets, there are now very limited parts and aftermarket support, and the rifle could be a bit smokey (like smoke coming off of the handguards) due to the piston set-up. The ability to add a folding stock, the similarity to an AR and the 18" barrel all appealed to me, though. Neat rifle but, IMHO, it could use updating in its original form.

Take a look at the Brownells BRN-180 (also now available with an 18" barrel) and some of the aftermarket options for it. The uppers aren't cheap but do go on sale occasionally. They can also heat up in the handguard area a little more quickly than expected. So far, though, they seem to work well.

The AR18/180 was developed by Armalite as an easier to manufacture alternative to the M16/AR-15. A stamped steel upper and piston gas system. It was made by Armalite, Sterling, and Howa. In the late 70s I had a Sterling that I used in local 2 gun matches. The folding stock had some side to side play. It had a proprietary scope mount welded to the top of the upper in front of the rear sight. The scopes are probably harder to find than the rifles now. The magazine catch was different than the M16. I cut slots in a couple of 20 round M16 aluminum magazines and they worked.
Today you're probably better off with Brownells BN180. You can use a folding stock that is more solid than the original. It has a top rail for optics and commonality with a lot of AR15 accessories like triggers and magazines.

Thank you both for the information so far. I am familiar with the development and history. I guess I should have made it clearer in MY OP, I have no practical experience or knowledge of the rifle.

I appreciate the recommendation for the BRN-180, but I am not interest in that bastardization. If I want flat top and hand guard rails I'll just build another AR15. I want the classic original configuration with build in iron sights and folding stock. Hell I would take the AR-180B if they are any good.

The lack spare parts is kinda of a concern.

that is the big issue,

My AR-18 is basically a safe queen, but it does get a few hundred rounds thru it every now and again

light, accurate, fun the flip the happy switch, and I am fortunate to have the correct scope w/ built in mount too,
