I have tried new clips and the colt clips perform best.
    Sounds like all your Colt may need a bit of rebuilding. Have you tried replacing gas rings? You may have a partially blocked Bolt Carrier Key or it may be loose. Without having experienced the failures first hand I am just throwing possibilities out there. You might also want to check the gas tube as well. I have had them fail in different ways to create poor pressure at the Bolt Carrier so as not to cycle it completely thus failing to feed.

    I used Bushmasters almost exclusively in my last job for testing. They can take a lot of abuse, may not be the prettiest when it comes to finish but they work. I rebuilt and re-barreled them often through out the year. We had a couple GI Colts and FN's and they were not any worse or better when it came to barrel life or maintenance requirements.

    I have rebuilt it a couple times and found carbon build up on the flange of the tube only. I shoot good ammo ALWAYS. Tube and carrier has good contact. Barrel nut hole is lined up perfectly to gas port hole. I am pretty certain I don't have a leakage problem and I even had a gunsmith rebuild it the second time just to make sure I wasn't missing something. It had him stumped too. I shot M16's plenty in the Corps and didn't have this much trouble on full auto. I have a friend that has an Hbar same configuration, maybe 4 years newer (1988?) and you can't get the darn thing to fail.
    The thing is, I have never had a FTE, only FTF's so I thought it had to be varying tensions on mags or slight differences in quality of mags. I have checked the bolt travel and it looked fine. STUMPED!
    We ALL shall see the Lord one day .... please don't make me set up the meeting.

    Is it not returning to battery or not stripping the next round out of the magazine?

    Sorry if I am beating a dead horse but I don't like being stumped

    The only time I had a FTF in my personal Bushmaster was ammunition related. A bunch of us were on the line, I had a magazine fail and a buddy tossed me one of his to continue the drill. Well it was loaded with Wolf steel cased ammo and my Bushmaster HATES that stuff! His Stag will shoot it all day long. That is the only ammunition my gun will not shoot, everything else ... BANG every time.
