I have a 8" 300blk that I run with my TBAC 30p-1. All the swiitchblocks I have seen are for 5.56 and longer barrels. Which Switchblock would work for my application?

Noveske does not make one for the .300BLK and you don't really need one. I'm not even sure you would be able to cycle the rounds reliably if you restrict the gas.

Brian is correct. I built an 8" on a rock creek barrel, and shooting subsonic ammo, in various brands you are unable to adjust the gas down to a measurable amount and still cycle the action.

Any .750 gas block should work for you. Pistol length gas system.

You could use it if you started with the barrel gas port wide open at 0.120, but the question is - why would one want one? What problem is it designed to solve?

5.56mm cyclic rate raises a lot when you put on a can. 300 BLK does so much less. The AAC 9 inch 300 BLK rifle can shoot from subsonic unsupressed to supersonic suppressed and all cyclic rates are within Colt M4 specs.

300 BLK does not need an adjustable gas block. The way to see this is that Noveske makes 300 BLK rifles, and they make the Switchblock, but they don't make a 300 BLK Switchblock.
