Building a .300BLK AR-15 carbine
I’m building a .300BLK AR Carbine. I want to be able to shoot both super and subsonic rounds. Will I need an adjustable gas block? Any other advice welcome.
Re: Building a .300BLK AR-15 carbine
Lots of things to consider before determining whether you need an adjustable gas block...just a few considerations;
A. Gas Port location?
B. Gas Port size?
C. Suppressor?
D. Buffer weight?
E.
F.
G.
H.
etc...

Carbine gas and adj. block. Find a 1:10 barrel if you can.

Not the best advice since he wants to shoot subs. A 1/10 will limit the selection of the better bullets available.
300 Blackout, not just for sub-sonics.

Because of the variations available, without knowing barrel length and if you will be using a suppressor, there really is no way of answering.
