I'm curious if anybody out there has shot or has an AR with the short bull barrel. If so, what kind of accuracy have you seen? Pics of groups would be great. Also, tell me make and model of said rifle. If you reload, what kind of bullets, powders does it seem to favor? Maybe I should have asked sooner, but I recently got my hands on a DPMS sweet 16. I'm just kinda wondering what kinda groups to expect at 100yds and maybe how far to consistenty hit Prairie Dogs. I know the shooter has alot to do with it but I am a decent shot.
