All I shoot is subs.
AR parts prices are once again low so I'd build if you have the ability. I have had ZERO malfunctions with my 8" Ballistic Advantage barrel using a standard gas block, standard buffer and spring, with everything from 190gr bullets to 220gr bullets.
I'm using AA #9 powder and even the slow rounds, @900 FPS, cycled and locked the bolt back.
I use a 1-4 Viper PST scope and limit my shots on hogs to about 75 yards. Fun little rifle to shoot and really quiet with my YHM LT .30 Cal suppressor.

Nice looking rig! I have lots of # 9 and 1680 powders. What bullets you running? how's accuracy?
