| Any love for the bushy upper here? I have a lower mated to an older colt upper, but would like to go piston with a flattop upper––any other options as well? |

I have a BM upper also, I have not had much time to shoot it, I have maybe put 200 rds through it.
but it worked flawlessly. I am wanting to put some rails on it, but need to know what will fit. have you mounted a rail on your upper? let me know if you have found something that will fit it. Will |
