  • There are two types of gas systems used in the 300 Blackout, pistol length and carbine length. Each one has its own advantages and disadvantages, depending on how you look at it. A carbine length gas system does not require an adjustable gas block and requires no adjustment if shooting supersonics.

The other point why I agree with iNeXile556 is that the 300BO pistol platform just doesn't seem to need any adjustment with pistol length gas. A standard carbine buffer and fixed gas block will work on most all 300BO pistols because the platform has a wide latitude of operation with supers and subs with pistol gas.

A properly set up 300blk (pistol length gas) will run fine with both subs and supers without an adjustable gas block (or buffer swaps for that matter).
