I have had an R25 for about 1.5 years. I have never had a single issue with mine. I have the little 4round mag that came with it and Pmags. All work. Mine feeds and cycles with every thing I have fed it. It also shoots .5 MOA, all day long using my hand loads. It was tight when I first got it but after a few hundred round through it, it has smoothed right up. The gritty feel of it cycling is in part caused by the much stronger spring and longer pull of the charging handle when compared to a AR15. They won't feel the same, no way no how. I feel the trigger sucks, .2 inches of creep is not conducive to good field accuracy. I was not confident with the stock charging handle so I got a BCM gunfighter. The Burris PEPR gave me the correct optics height. The camo will scratch so I put electrical a strip of electrical tape along the comb of the stock so the CH would not mess it up.
