Would it be easier to maybe get the muzzle device in the correct thread pitch? Might have better luck with the short notice.
prob would be but I already have the muzzle device I plan to use and will be having the barrel threaded by Morgan soon just wanted to use it this weekend. I had also bought a thread adapter thinking the YHM barrel was 1/2-28 but it's 1/2-36. I will prob shoot it without a muzzle device this weekend and the. Take it apart and send it to Morgan.
