Any input on these brake attach versions? I have 2 AAC cans and am somewhat unhappy with them. I have several precision ARs and want something a bit more accurate and one that can handle a 300wm. Calibers to be shot from the AR in this suppressor will be 243wssm, 6.5 Grendel, and a 6.8 based wildcat. Bolt calibers will include 243 win, 270wsm, 7wsm and 300wm. Any suggestions advice? Is the p-1 better than the ba? Thanks!
