Only had enough time to run 100 rounds of Federal American Eagle 115gr. FMJ through it today.
Zero malfunctions (stock recoil spring), comp stayed tight (cleaned threads with acetone prior to the Locktite and torqued it tight).
RDS zero remained the same.
Muzzle rise was tamed to the point the dot never left the window at any time, pretty noticeable.
I'm looking forward to trying some +P and +P+ when I get a chance to see if more gas equals more better.
