So far so good
According to the installation instructions you are supposed to tighten the front nut hand tight before torquing down the set screws. When I did it that way, the gas tube started to become noticeably loose after 20 rds. So I reinstalled and this time used a wrench on the front nut, not crazy tight though, and I'm having much better luck. Staying in place and holding zero after 100 rds, and able to repeatedly hit a steel target at 130 yd with a trs25 red dot.
