I've got a barrel diameter of .737" on a RRA Pred. upper.  I was thinking of adding a compensator to it for the upcoming season.  



All I have found online are for diameters of .750" & that's a difference of 0.013" which doesn't sound like much until you're talking about a bullet striking it.  





Do I have any options besides getting the barrel threaded?

Sell the barrel and buy one with a threaded muzzle.

or have your barrel threaded

No way I'd use a clamp on muzzle brake.

That's what I was thinking would be the best answer.  I cant see a clamp on being concentric to the bore even if there was on in the proper barrel size.



Thanks

I had tried one during the ban days (94-04) and the thing went flying down range one day as I fired the gun. Don't trust them.

Same here. Mine lasted 2 shots. Second shot made a huge hole in the target.
