I've been struggling getting better than moa accuracy out of a dpms 243 barrel. It came threaded 5/8", but the fit is so loose that I got in the habit of checking to make sure the suppressor didn't come loose after each group. To be more specific, I get good groups occasionally, but when I try to verify, it always falls apart.
And to make matters worse, I swapped out the barrel as I have a couple extras, with the same results. It seems unlikely 2 barrels in a row would be so mediocre and inconsistent. I've squared the upper, tried different scopes, etc to rule that out.
So it just dawned on me that the terrible threads might be the source if they're allowing movement, or causing inconsistent vibes upon firing. Anyone experience this before?
