Between a BCM BFH 11.5 MCMR upper and PSA 10.5 with FN barrel and Geissele rail is one much better than the other? I know that dwell time in theory should be better with the BCM. I am about to pick up the BCM 11.5 on Monday and wondering if it will have any significant advantage over the PSA that I mentioned which I already own and love. Is one of them likely to be more accurate or better for suppression? Just curious as to your thoughts as I might only end up keeping one of them after I pick up the BCM. Thank you
