Blackout 300

So long as your gas block diameter and gas tube length are the same for the 300 & 5.56, it should just be a straight barrel swap.

Thanks for the input.

I would guess that has a pistol gas system as short as the handguard is. The gas block itself you could reuse, but the gas tube would be too short for rifle or carbine length stuff. A standard low profile gas block and tube would be inexpensive to replace.

I've got a bunch of 1x fired converted 300 brass if anyone is interested. I've got @ 600 pieces I likely won't be using. Cleaned, deprimed, trimmed to 1.360 +\- .005, swaged. It was converted on Dillon 1050.

This taken? I have a 300blk but i hate the prep it takes. shoot me a pm.

Just buy you a new upper and sell the current one. Much easier than switching just the barrel...
