I have a LaRue UU 6.5G that I absolutely love shooting. It's a half MOA rifle and does it so easy. I will finally get to push it out a little further in a few weeks and get my drop data.
I tried up to a H2 and wont run reliably with ar comp. Tried different springs and lowers even. I guess just not enough dwell time. Runs fine with cfe223 or varget. I just decided to stick with varget and see if it will run with ar comp after i get my can. Varget works real well and shoots fantastic so no big deal.
