I'm deciding on what muzzle brake to put on the Sport I'm getting and as I was talking to a friend he brought up good point. .Some are really loud! I'm a harp player and I have seen my share of loud stages over the years along with a Dan Wesson 357 max I didn't always shoot with ear muffs. I'm not concerned with hiding my flash or recoil reduction or even how it looks. .Just how quiet I can make it.What will be my best choices? Low cost is a big factor I would be happy with a thread protecter if that was the quietest option.Thanks all!

If you aren't concerned with recoil reduction, then what you are looking for isn't a "muzzle brake" per se. Brakes are inherently loud due to them pushing sound, and more importantly gas outwards, perpendicularly to the bore. What you want is a linear comp. The Levang was probably the first to really focus sound down range. I don't have any experience with one but from what I've read they are very effective. I have shot a Kaw Valley linear comp and can attest to the fact that they are much quieter for the shooter than a standard flash hider or muzzle brake (and in my opinion are quite attractive both in design and finish).

What you want is a suppressor.

gdog is correct a linear comp or a suppressor if your state allows for them, SilencerCo. has the SAKER models good value.

If a suppressor is not an option, then a linear comp is the ticket. I run a Troy Claymore on my Tavor. The short birdcage + relatively close distance to the muzzle made the report quite loud. The Troy claymore focuses the combustion gas blast and report downrange.

"Quiet" and "rifle chambered in .223Rem (5.56NATO)" are things that should never be used in the same sentence.

I have a Levang and it works very well. It will not give the recoil reduction of a Miculek or other pure completion breaks but it gives some reduction and is much quieter than a plain muzzle end. They don't cost very much either at Brownells.

Yessah, and that's the sound of Freedom.

No.

A muzzle brake, by definition, will increase perceived noise.

Nah........5.56 is the sound of suppression fire.



7.62 is the sound of freedom.

.50 cal is the sound of freedom, from about a mile and a half away!!!

That's the first I've heard of linear comp and I'm interested. Do you know what thread size and pitch the MP15 barrel is?

Is it standard like 1/2 28?

The tests are impressive. Effective muzzle break w/o much concussion.

And needless to say as someone whose hearing is important to their profession , foam ear plugs AND muffs of a high Db rating.

There are basically two styles of muzzle breaks. One reduces muzzle rise and the second reduces muzzle rise and recoil. They work by directing the direction of the muzzle blast gases. To reduce muzzle rise the gas is directed upwards to offset muzzle rise. The other type directs gas both upwards and somewhat rearward. Not straight back but back at about a 30 degrees rearward angle. This somewhat rearward direction causes the gases to push the barrel forward, offsetting and reducing the recoil.

This problem is the sound follows the gas, and upwards produces more noise to the top of the barrel, and the other style sends noise upwards and rearwards. It is more noisy for the shooter, but even worse for someone standing 10-20 feet to either side of the shooter. Not only more noise, but they can also feel the percussion waves.

I have a strong recoil reducing brake on my AR10. It works well but punishes anyone near me.

In all my research on my AR I have never heard of a linear comp...But it's perfect for my use! I don't think recoil is a factor with the 5.56/223 so I'm really surprised it's not a more common add on..Thanks for sharing, some models look awesome.

If you're looking for recoil reduction and reduced muzzle rise, this is the deal, but you have it loud. Lantac Dragon. $125



A little quieter, but not as effective at reducing recoil or muzzle rise. Linear comp. $35

Muzzle Brake = More Noise

Can you easily change muzzle brakes/comps? Like you change choke tubes?

Not as easy as choke tubes, but easy enough. All you need is a wrench the right size and something to hold the barrel while you set/remove the muzzle device.

What linear comp is that ?

The "linear comp" shown will do very little to reduce recoil. It will alter the frequency of the sound and make it more intense.

If you want perceived sound reduction and don't really need recoil or climb reduction, a device similar to the above but with a completely open end will help. Think WW2 BAR flash hider. It is just a straight tube of much greater than bore diameter. What this does is change the frequency to a less intense level due to the increased bore diameter and add the equivalent of the volume of an increased barrel length where the powder has more space to burn. Longer barrels have less muzzle blast and larger bores have less intensity of sound.

The classic example of this phenomenon is a short barreled .22 magnum handgun. Same for a .30 carbine or .32-20 handgun. The blast from any of these is so intense as to be almost unbearable without ear protection.

A Krinkov style muzzle device might work.

I bought it off Ebay, in all honesty I don't remember the name of the company that sells them. I have it posted in one of the threads here. As a side note, Brownell's has the actual Levang Linear Comp for sale for $34.99.
