AR-15 Eagle Arms Feed/Eject Problem (FL)

[orangeparkplink]

I purchased an Eagle Arms AR-15 and it fed the first 9 rounds of wolf ammo 62gr fmj with no problem, and then the next 10 jammed every round. I took it apart and thoroughly cleaned it including the gas tube and got the same results. I purchase brass cased commercial ammo and it ejected fine, but did not feed the next round. Any help would be appreciated.

Is the rifle used? The symptoms you describe indicate short recoil, or 'short-stroking.' It's caused by something in your gas system, so check the gas tube to see if the pin at the front sight base is broken (or the tube itself is broken); check for excessive gas leaking at the front end of the gas tube; check the bolt carrier key to see if the screws have come loose, or weren't properly tightened to begin with. Also check the bolt gas rings to see if they're badly worn or damaged/missing.

Get a new magazine.
Make sure the gas tube roll pin is still in place in the front sight assy.
Make sure the gas ring gaps are staggered.
Good luck...

Guys, it was a lose bolt carrier key. I tightened it up and worked flawlessly. Not sure how I missed that in the first place. I must have been too focused on the ammo. Another issue resolved from the community at The High Road. Thanks again.

Bolt carrier keys are supposed to be staked to prevent exactly what you experienced. Sometimes they slip through un-staked. Best get it done to prevent future problems.
