Mounting a Compensator on AR-15

I have a Bushmaster AR15 16" shorty carbine. Is there anyway I can mount a non-permanent compensator on it. I don't want to weld or anything like that. No pins either which might mar the barrel.

Is there a device like this on the market? I have an idea on how to make one, but I would prefer to find something already invented.

Any suggestions would be appreciated.

Thanks.

DPMS (www.dpmsinc.com) Make a unit that is held on with set screws. There are others as well, but you'll have to search around for yourself.

Set screws would probably mar the barrel. Thanks anyway.

What's wrong with marring the barrel? A simple touch of bluing will fix it right up. You won't get a reliable brake for a post-ban that doesn't use setscrews. Smith makes a good post-ban brake., but it does use four setscrews. "Marring the barrel" isn't a big deal, if you want to install a brake.

I remember reading about making a sleeve for a pistol barrel that was press fit while it was hot and the barrel was cold. Cools off shrinks, stuck on there good.
Maybe you could look into having a sleeve like that put on close to the muzzle to mount the compensator on. Then if you ever decided to take it off, you can have the sleeve removed and you won't have any dents/gouges in the barrel, maybe just need a touch up on the bluing :confused:

many people machine a ring around the muzzle and use set screws
or you can wait till sept 14, 2004 and thread the barrel

even with loc tite, the set screw compensators can loosen and travel down range

"even with loc tite, the set screw compensators can loosen and travel down range.."

If you paint the mating surfaces of the barrel and compensator with 640 Loctite (sleeve retainer), I guarantee you you're not going to be sending the comp downrange. You'll have to heat the comp with a propane torch in order to remove it. I use 271 (red) Loctite on the setscrews.

I was thinking in mind of some kind of high tech heat resistant O-ring. Slip the comp on, and then depress some kind of lever that would compress the O-ring and hold it tight.

Probably would not work given the physics involved. Just a thought.
