I'am building my first ar in 300 blackout.I have a noveske bcg in a viltor 10 in. vis upper with a 12.2 in. noveske barrel and i'am planing on getting the barrel cut to the lenght of the upper with room for a can.my question is would an ajustable gas block with tubbs spring have the same effect on felt recoil as going with jp low mass bcg and buffer and an ajustable gas block? how would y'all set up the weapon for the smoothest and least amount of recoil. thanks for any and all help in advance.
