View Full Version : AR-15 pistol

January 13, 2000, 01:46 AM
I recently purchased a pre-ban Olympic Arms AR-15 pistol,(love ar's and it was just so cool!). I'm having problems with it feeding all the way forward, and sometimes it will not eject. I cleaned and lubed it but still bang-jam-bang-jam. Did I buy a piece of junk or is there hope in reviving this little guy.
I have no past experience with Oly arms.

It's probably a lemon and probably not the fault of Oly arms either. As far as I can tell the majority of the AR pistols are. Most of them are kit guns built by someone who thought they knew what they were doing just because they had assembled AR rifles before. The pistol requires a lot of help to make it work right. I was going to build one myself but gave up when I consulted with a couple people who work on them for a job. Heres a couple things I learned from the people who should know.
1. The pistol recoil buffers avaliable are too short and the springs are weak and get weaker with use. The fix for this is to replace the buffer tube with one almost as long as the one for a CAR15 model. I think you can still get them from DPMS but you have to ask them.
2. The gas port is so close to the end of the barrel that the bullet leaves before the action can cycle, and the port is either too large or too small. I think it was too large.
One of the guys I talked to said they solved some of the problems by silver soldering an expansion chamber into the gas tube.
3. The barrel being so short, the powder does not burn cleanly and fouls them up royally.
Sorry for the bad review here, hope yours works out. If they worked right they'd be very cool guns. Good Luck.

I tried to home build a kit gun and ended up send the ENTIRE gun back to the comapny that made the kits, after several weeks and some $$$ they sent me back a reliably working weapon.

Thanks for info. I think I'm going to take advantage of my 72 hour inspection period and return the gun. I don't like to do that but the person did give me that option. I found a low serial # M1A that I think I'll try. I've got a few 223's, so maybe it's time to step up to a bigger cal. Thanks again!
