[QUOTE="QuietTexan, post: 2447306, member: 116181"] What powder are you planning on using? A1680 cycled 100% of the time from 1150 down to 975 FPS. SW Blackout failed miserably and never cycled twice in a row. BCM 9" 300 BLK upper, H or H2 buffer?, FA carrier, standard carbine spring, no suppressors for those first tests. Factory 200gn WWB subs cycled also. Not going to lie to you, there's a lot of better options if you can't run a suppressor AND a short barrel. [/QUOTE]
