Best SBR legal sound limiting?

[Petamocto]

I'm about to get into the SBR game, having put a deposit on a Daniel Defense MilSpec+ Mk18 (the brown one).

My friend has a budget Norinco C8-like SBR, and when he brings it to the range, and it is noticeably louder than everything else that's shooting on the line, including lots of 30-cals. Not quite "F__k you, everyone else" loud, but something I'd like to limit if I can when I get the DD.

I've researched the forum and Google, but most of what I find is either US-based silencer/suppressor stuff (not legal here), or reviewers focus on flash reduction and not sound.

The two main brands I keep seeing are the Smith Vortex, which seems to hands-down win the flash-reducing competitions, but it's hard to find sound reduction. There's the Noveske KX3 Flaming Pig that has mixed reviews, but many say it is just a big heavy block of metal that does not do what it promises.

Without getting into a legal debate, and comparing us to Europe where suppressors are mandatory, does anyone know of a SBR solution that works to lesson some sound while staying inside the rules? I'm hoping there is some sort of creative way to break up the sound waves or direct the powder in such a way that it solves the problem in a different way than a silencer/suppressor.

(For clarification, I am not asking for the impossible, just even something that could help with a few decibels).

Thank you.

Best bet is to push as much sound forward as possible, This means you cant use anything with vents, holes, or openings on the side at all.

Linear compensator. Allen Gunworks and S&J Hardware both make good ones for around $60. They push the noise away from the shooter.

I have one of the AGW linear comps on a 14.5" build of mine, noticeable difference over a plain jane A2 bird cage.

I also have a Troy claymore on a 7.5" AR. I found the difference in performance between the AGW LB and the Troy unit to be unnoticeable with-out testing equipment......

The Troy wins hands down in the "tacticool" department but I would have to say it's not worth 2x the AGW..... For that kinda of cheddar you could buy 2 of the AGW comps!!!

Oh and they also do reduce the felt recoil a bit. Not as much as a traditional brake would but it is a .223, there's not that much recoil as it is!

Cheers!

Noveske KX3

The Dlask XB-1 and Noveske XK3 are very similar in design and they are both designed to not only reduce flash but also direct all the gases and sound forward, away from the shooter. All the Linerar breaks do this as well. Thats your best bet. Get the sound and gasses going away from people (NO side ports on the break). FWIW, the KX3 and XB-1 pretty much eliminate flash... its pretty impressive how well they work.

That could get messy.

And expensive.... But it begs the question. I you built a very well insulated box with a hole for your arm.... And a hole for the bullet.... Put your gun inside and fired... Is it a suppressor?

This is both sarcasm and a curious question.

 

[condomboy]

going to all this trouble... why not just buy a longer barrel if you're worried that much about sound from the shorter one?

Chris's gun has a NEA brake that works well but it throws the noise sideways. When I shot it, it was half the noise that it was when I was satanding beside him, watching him shoot.

Linear brakes seem to work best for sound so...

Wait till the Friday shoot and compare mine to his (we will be bringing both). I have a shorter barrel (11.5) and make way less lateral noise with my ATRS Eliminator.

His IMO does a better job of keeping the point of aim on target for follow up shots.

Trade offs.

 

[jawsman]

Look at the Alberta Tactical eliminator. I have one on my 8.5" shorty and my buddy just got one for hours 7.5" shorty as well.

Fair enough question, but I'm hoping not to have to add that much length. Keep in mind that I'd already be replacing the birdcage I have, which cuts off about 1.5", so if I add a new better one that's 2-3" it's not the end of the world. I certainly don't want to add a 4-6" monstrosity, at which point you're completely right as it defeats the whole purpose.

For those pushing the KX3, as I stated there are a surprising amount of reviews online that state it doesn't really do what it claims to do (or at least as well). It seems kind of sketchy that on their website they say their flaming pigs are meant for all barrel lengths, which does make it seem like they care less about truth and more about money.

The way the law is written, yes, that's a suppressor and it's illegal

 

[Suputin]

There is nothing in the law that states a silencer must be attached to a firearm. There is no decibel limit specified in the law. Any device that has as it's function any kind of sound reduction could be classified as a silencer.

Just an FYI here is what the definition of a prohibated device is as per the Crimianl Code as it pertains to this discussion:

(c) a device or contrivance designed or intended to muffle or stop the sound or report of a firearm,

http://laws-lois.justice.gc.ca/eng/acts/C-46/page-42.html#h-37

If the item or thing fits that description it is prohibated

Theoretically yes, the wording is IIRC "ANY DEVICE"... so silly.

ETA

Beat!

A suppressor is any device that reduces the report of a firearm. So a pop bottle on the end is illegal. Now it also says that a muzzle break isn't a suppressor. It's not that it's illegal it's just a prohibited device. Make it legal to own a prohibited device they're now legal same with high cap magazines. It's not a prohibited firearm which would be machine guns, pistols that have a barrel to short ect. They're prohibited weapons. I find a muzzle break that directs the blast forward or forward and sideways works best. Like a birdcage. Now you can always just get a longer barrel and it makes allot less noise.

Do you even read what you write? I have no clue why you still feel it necessary to provide us with your BS info about the law.

No it doesnt

It's not that it's illegal it's just a prohibited device.

Which makes it illegal

Make it legal to own a prohibited device they're now legal same with high cap magazines.

Really? lol make it legal to rape and pillage and raping and pillaging is legal.

It's not a prohibited firearm which would be machine guns, pistols that have a barrel to short ect. They're prohibited weapons.

Even this is not correct, they are prohibated firearms. You cant even decide what they are in the same sentance.

PWS CQB comp pushes the most noise forward very effective. The original design of the CQB comp was rejected by ATF deemed to be a suppressor due to the level of noise reduction . PWS did a redesign to the baffle cone inside to meet the ATF requirement . I had a 7.62 x 39 Diablo from PWS with 7.5 inch barrel as well as the 223 version both pushed noise forward.
