Hey guys, putting a can in jail this weekend. Just finalizing up my trust then off to my dealer. Currently have a tbac ultra 7 30can on hold. This will be for a 6.5 grendel AR and a 6mm arc AR. I've heard the 30 call can does better on the grendel for back pressure.
Currently my rifles have standard gas blocks with carbine length buffer tube, standard springs and standard carbine buffers. My 6mm arc is a monster 20" rifle length gas and my grendel is a monster 16" midlength gas
Now from what I can tell, I should swap out the gas blocks for adjustable to keep from being over gassed. The 2 I am looking at are the superlative and the aero. From what I can tell it seems most prefer the superlative.
Can anyone give some insight on this. Also my dealer also has the 7 in 6.5mm if that would be a better choice.[ATTACH=CONFIG]19483[/ATTACH]
