    AFTER you scrub out the chamber...

    the problem with steel case ammo is it doesn't expand as much as brass so there is leakage back into the chamber. this builds up and reduces chamber diameter.

    not saying this is your problem but is symptomatic of the ammo you are using...
    never push a wrench...

    As for brass after steel case, M193 fired after a lot of Barnaul here.

    UPDATE:

    I know this thread is a bit out-of-date, but I wanted to update it just in case anyone else is/was having the same issue.

    I ended up sending my BCG back to Palmetto State Armory, accompanied by a letter explaining the issue that I was having. The service guy who received my package did some testing with my bolt and determined that it was indeed a faulty piece. They sent me a brand new one a week later free of charge.

    The tech guy sent me a return letter saying that while rare, defects can occur during manufacturing. With that in mind, I'd suggest that anyone who has this problem contact the manufacturer of their bolt and see if it might still be covered under warranty.

    I can say first-hand that PSA was very accommodating to work with and were very responsive in getting my problem fixed quickly.

    Thank you to all of those who contributed to this thread the first time around. Your input was greatly appreciated!

    Ok, the OP and IQ posted while I was writing my post, and after I posted is when I realized this was an old thread, so I’m removing my post as it is useless. Wish I could just delete it.

    I'm having a similar issue with a new rifle. Round is free to move but BCG is stuck until I slam the buttstock to get it to release. I'm getting ahold of the manufacturer next week.

    I had this problem also, but it was not the gun. I had just reloaded 200 lake city brass and I had backed my sizing die out before starting. I had noticed that the sizing die was coming in contact with the shell plate on my LNL AP press so I backed it out about a 1/2 turn to clear the shell plate. I took those rounds out and one in 10 or so would not go into battery, hanging the BCG group a 1/2 from closing. I would have to work very hard on the charging handle to get it out.

    I retrieved another AR from the house thinking I had a dirty chamber with the first one. And my second AR did the same thing. So I knew it had to be my reloads. I went back to my reloading shed and that's when I remember what I did with the sizing die.

    Lesson to learn from this: do not go messing with something that is working fine just because you think it does not look right. I am just glad I had not reloaded a large number before finding this.
