Very pleased, so far. I sent my backup to the backup stock and receiver to have the CIRS installed into. I did this because It had the beefiest stock, which I thought would yield a better result. I had never even shot it. Anyway, yesterday when I got it back, I took it for a trial. Unfortunately, I discovered on the first shot that it had the lightest trigger pull for a shotgun I ever encountered. I'm guessing in the 4 oz. range. I have a trigger pull gage on the way, so I'll have something definitive on Friday. Because I had never fired this receiver, I brought a spare trigger group. But, the release on the installed one proved stubborn and I didn't have anything that I could use to persuade it on the range, so I only shot one round and even knowing of the light trigger, I had 6 or 8 "surprises". Also, my back was bothering me. So, between my back and the trigger, I cut things short. Maybe I'll get to shoot it this weekend.if my back is better. I'll report more later...
