What are the pros/cons of DPMS and RRA varmint uppers with 20" barrels? Is one more accurate, more reliable or better built? The RRA has a Wilson barrel. I'll be using a Lauer lower with it.

either or...personally, i'd opt for the RRA

if i remember right, they both use Wilson bbls, h/w, i have noticed that the fit and finish on the RRAs tend to be a little more to my liking (dark black finish, tight fitting) and the BCGs seem to not only wear a little better but seem to be a tad better (staking, extractor, springs/pins, etc) quality

Thanks, Alpha, I will go with the RRA, which was my gut feeling.
