AR muzzle device question.

[Bullcoop]

Is there any way to use a 1/2 x 36 muzzle device on a 1/2 x 28 barrel?
I'm guessing no, but if there is some sort of adapter could someone point me towards it.
My problem is trying to find a variety of compensators in 1/2 x 28 in 9mm!

Another question is could I just bore out a 5.56 muzzle device to 9mm. thats 3.5 mm of material being removed and I dont know how much of the muzzle device I can safely remove.
Anyhelp would be great. Thanks.

No you can't adapt it. You could have that portion cut off and re-threaded or you could open it up. You need to go oversize on the bore or the bullet will contact (destroy) the compensator. Take it to a gun smith.

I found another option but I'm not sure if the tolerances on Pistol (Glock, Berreta etc.) compensators will stand AR use.

I dont see why not, both are 9mm and mine is a 5" barrel, not like I'm putting it on a carbine. If I'm missin something lemme know.
