My 300blk is threaded 1/2 x28… but no option for a .30 in 1/2x28? Is the diameter of the hole on the end the same across the board? — 1 Answer

The diameter of the central channel of the Phase 5 Weapon Systems Inc Littleboy Hex Brakes varies depending on caliber. The Phase 5 Weapon Systems Inc Littleboy Hex Brakes model that is for 9mm/ 7.62x39 and is threaded for 1/2x28 might work for .300 Blackout. However, I recommend contacting the manufacturer to confirm compatibility.
