Just wondering if anyone else has noticed this. Nothing major. I know they warped quite a few at heat treating lately. I bought a couple because they were the only ones available at the time and they were not near as nice as the 3 I bought 6 months ago. The first ones fit nice, no bends, had some kind of coating (not parked). I started some more builds tonight and pulled them out. First off I had to blast them to get the rust off (no coating). One had a couple of pits, nothing real bad but still irritating. Next I noticed that they were bowed in on the ends much worse than the previous three ( with the trunnions in I think they will be fine but, still worse). Also I had a plate trimed to put in my trigger guard rivets (from my last builds) and it will not fit in either receiver. The receivers are almost 1/16 too narrow for the plate (but the trunnions still fit and line up fine). Have they changed up production and bending procedures as well as heat treating. Once agian nothing bad just a few observations.
