Armalite AR-180B Problems

[Maxwell Gunn]

I have an AR-180B and a spent cartridge will get caught in the ejection port after a few rounds are fired through it. I have to rack the bolt back to clear the cartridge but a lot of times a live round will also get jammed in the breech which I have to pry out by hand. I've fired approx. 300-400 rounds through the rifle so it shouldn't be a break in issue. I've also used the supplied mag from Armalite, my other aftermarket mag, and the mag from my dad's DSA ar-15 and the same thing happens with all of them. My 180B is out of warrenty so I can't send it back to Armalite. I only fire American Eagle Federal ammo.

Just curious if anyone has had experience with this, or knows what this might be. Any info is greatly appreciated.

Thanks.

I have seen this before, and have had dudes, ' waller out' the back of the ejection port a bit, or the top of it. this will be your only fix.

Happens a lot in the ar180b. As the gentleman above stated the only way is to modify the opening. May be time to trade for an AR15 style.
Blessings.
