Will I need an adjustable gas block on a 12.5" pistol build? - jurassic - 11-24-2014
I have a 14.5" Sabre Defense barrel I'm going to cut down to 12.5" and build a pistol. Will I need an adjustable gas block, what buffer is recommended, H2-3?

You will have to figure it out with your gas system, loads, and recoil system.
Most people open the port for that length. I would try it first before messing with the port. You also will do yourself a favor by finding a way to seal the gas block and tube off from gas leakage. That will allow you to use a smaller port and no need for adjustable gas.
I would recommend having at least those 2 buffers on hand, or using a JP SCS.

Thanks, I usually use green loctite on the gas tube at a minimum, but I'll run it first.
