    1. Replace worn parts.

    2. Remove the o-ring.
    My rifle has a 1:7 chrome lined heavy carbine barrel with a 5.56 NATO chamber. At the time I was shooting federal 55grn FMJ .223 ammo. I did perhaps wonder if I had too much grab on the extractor.

    If it's a BM. (You didn't specify.) It could be marked 5.56mm chamber but still have a .223 chamber.

    very possible with a Bushmaster

    ditch the O-ring they are very seldom needed in the M4 and alot of times not needed in the 10.5" guns either.

    I built the weapon from parts I got here and there. There isn't a bushmaster part in the whole weapon to my knowledge.

    ....a 6yr-old thread...

    ...that quite clearly and specifically has the word "Bushmaster" in the title....?

    ....when your gun isn't a Bushmaster....?

    Makes perfect sense.
