Suppressed subs from an SBR that actually cycle the weapon is fun, you can't argue with that. Thats whay most (especially us youts under 35) have taken a liking to them. Unless you already have or plan on doing the work for a suppressor and SBR lower, 300BLK is pointless. I prefer 5.56 for mostly everything from an AR but a 6.5 Grendel project has always been on the back burner for me.
