    I have a DPMS Pantherlite 16 inch carbine. It has an A1 upper with an A1 stlye birdcage flash surpressor. I think I want to change the surpressor to the Bushmaster shorty style that is about 4 1/2 inches long with internal threads that makes it look like the old commando style rifle. The new surpressor says it has 1/2 x 28 tpi. Is this compatible with my DPMS threads?

    It should be. 1/2x28 is pretty much the standard for AR threads these days...

    5.56/.223 AR barrels (if threaded) should always be 1/2 X 28. The 9mm's ae different and the .308's are different.
