Does it look like its worth using? :D
Im going to have a local gunsmith lath and thread my AR barrel, the brake has a blind pin.
Here another question, it has the tottal of 8 vent holes, as you can seen in this picture, how should the holes be lined up? Im thinking, that it should be solid part lined up with the top & bottom, that way no flash to blind me in low light situations and for the botton, no dust blowing back up in the prone position.

Just curious, did you have this brake made or was it purchased? You definitely want to make sure your brake will meet BATF scrutiny.

The way you described it being lined up will work just fine. You will however still have a dust signature due to the design of the brake. Take a water hose and shoot a stream of water through the brake and you will see the pattern that the gasses will make.

The most efficient brakes usually have a larger ports directly to the sides and smaller ports upwards or at a slight angle with no ports to the bottom. The design of the Bushy AK brake is a perfect example of this.

This is a advertised as a postban brake, not a 100% sure, but think Hesse was using these on some of their ARs.

Instead of a "brake" of unknown efficacy, why not get a good "comp" put on?

Both JP Enterprises and Benny Hill (Triangle Shooting Sports) have very good comps that are widely used on AR-15's by top-placing 3Gun competitors.

Ahhhhhhhhh, that's nice. Thank you! You didn't call it a "break"!! :D



Compensator is just a fancy name for a brake. Both do the same thing. Reduce recoil and muzzle climb. Uh, if they're designed correctly, that is.


That one's ugly, though. :D

Brake vs. Comp?

Ideally they should do the same thing. In practice, it seems like those marketed as "comps" operate way better than those marketed as "brakes." Yeah, your generic Bushmaster or DSA muzzle brake is going to reduce recoil somewhat. My FAL recoils less now tha it has a brake. The ones marketed as "comps" generally have been designed specifically for competition and have more R&D behind them.

Another example would be a generic ported barrel in a handgun compared to a fully comp'd IPSC race gun. Yeah, the ported gun will have less recoil than its non-ported counterpart, but the IPSC comp'd race gun will have virtually no recoil - it's just damn loud.

Smith Enterprises makes a good brake that uses four setscrews. I wouldn't want to have my AR barrel threaded and a brake welded or silver-soldered on. My Smith brake's attached using 640 Loctire on the mating surfaces and 271 Loctite on the setscrews. No gunsmithing required, and it actually looks better to me than your brake.

The JP brake is actually called a "Recoil Reducer" by JP. They make a post-ban that also uses setscrews. It'll fit Colt post-bans, but not Bushy post-bans. Mr. JP hisself told me several years ago that he was going to make one for the post-ban Bushy's but so far, to the best of my knowledge, he hasn't come through. Since Bushy makes more AR's for the "civilian" market than everybody else combined, you'd think he'd do one for the Bushy.

I just sent my AR upper off to JP for their BC Tac Comp.

The normal way they attach it is they put a post-ban compliant 5/8x28tpi thread on the barrel, then apply red lock-tite and screw on the comp real tight. Presumably you wouldn't have to lock-tite it on, that just keeps it from unscrewing itself.

This method is BATF approved (ie, it does not count as a threaded muzzle); there are no flash-hiders that have 5/8x28 threads.
