Adjustable Gas or No?

[PigOPs]

I have in my possession a 14.5" Sabre barrel that, after checking to make sure loads could be loaded to normal lengths, I am sending off to ADCO to be chopped to 12.5". Best I can measure my gas port is .070" and is carbine length. I am trying to steer away from using an adjustable GB but will primarily be using this upper with a Saker 7.62. What say ye horde... Will it run suppressed/unsupressed (supers only) without an adjustable gas block or should I spring for an SLR???

Variable-- Do you use an adjustable block?

In my research looking at sbrs and suppressors, I find most everyone use a adjustable gas block/adjustable key.
