No I didn't. The instructions for the gen 2 didn't say anything about that. I may give that a try at some point.

I shot 60 rds using the standard bcg with no problems. It didn't feel like it was shooting as flat as it did with the ss bcg.

I am planning to try my Taccom standard bcg instead of the short stroke bcg, hopefully this afternoon. The upper runs fine on my other lower that has standard buffer and spring.

Doing a new lower build, first time for me. Using a stripped Aero lower, cmc 9mm trigger and the Scheel rdbs g2 I just got. Using an existing upper, Taccom upper, Taccom ulw barrel, Taccom short stroke bcg. Schell rdbs setup per instructions, heavy spring hole 1, light spring hole 2. Ran about 30 rds fine then the bolt started to not go fully forward. Figured I would finish break in. Fire a round or two and clear round not chambered. Then I had the bolt lock back into the buffer tube. At home I was able to press the trigger down with a screw driver and get the bolt forward. So 2 problems, weak bolt return and bolt recoiling too far any help would be greatly appreciated.
