Beginning to have some concern that the barrel on this rig is at the beginning of the end. This summer this rifle has been in five tactical matches (~300 rounds for a total round count of ~1800). Each of these matches has been a real pounding on the barrel with each match having more than one stage with 5 to 10 rounds fired in quick succession.
Recently took the rifle out to verify its zero at 100 yards and it shot just under .75moa. Shooting was a bit rushed as I didn't have a lot of time. I can only hope that being rushed caused me to not shoot my best.
This coming weekend going to shoot another tactical match with an expected round count of 150+ rounds over three days. When I get back, will conduct some serious 100 yard testing.
Anticipating the worst, going to be ordering a new barrel now.
