I agree the Break shield seen here below in the story is not a suppressor but if the ATF stood behind the tester with a meter and one test with the shield off , the second test with the break shield in place it's going to be a lot less DB's behind the shooter.


It says in the artical that it redirects gases & sound away from the shooter.


The ATF is going to take the tact (possibly) that any drop in DB's in any direction is a suppressor?





We all know some of testing done has been less than stead fast honest, like using soft primers to get a gun to double.

If that were the case, then all flash hiders would be suppressors since there is less sound behind a rifle with a flash hider than a rifle with a brake.

ETA: Seems like a pointless idea, anyway, reading the article.

I don't see how it could be considered a suppressor.

No baffles or end cap.

I've said here in the past that, by a perfectly strict adherance to the (constitutionally) overbroad definition of a silencer in the NFA, headphone ear muffs and ear plugs are silencers.

That thing has been around for more than a year, and there are others like it out there. And shittons of linear brakes, and bloop tubes.

The answer is NO.

Looks like a muzzle break... given how acoustics works, the 'report' noise is going to go somewhere - it'll come out the front in a wave - so anyone to the front of the shooter should hear the blast. Lessening the relative report for the shooter or those behind him is not the same thing as reducing the overall report of the weapon.

It'll still sound like a CRACK not a Pop.

A silencer really does muffle the sound emitted by the expanding gases. That thing just redirects them.

There's less sound forward of a shooter with a brake too.

ATF is retarded.

No, they don't do anything to quiet the report of a firearm, they cover your ears. If they went on a gun you'd be making sense.
By that bizzare interpretation distance would be a silencer.

For the purposes of the National Firearms Act the term Silencer is defined in 18 U.S.C. § 921(a)(24)

The term “Firearm Silencer” or “Firearm Muffler” means any device for silencing, muffling, or diminishing the report of a portable firearm, including any combination of parts, designed or redesigned, and intended for the use in assembling or fabricating a firearm silencer or firearm muffler, any part intended only for use in such assembly or fabrication.

Earplugs & muffs do not diminish the report of a firearm in any way, just the wearers perception of it.
For a device to diminish the report of a firearm, it has to actually diminish the report of the firearm.

Pillow on end of gun, could be a silencer.
Pillow over your ears, can't be a silencer.

Would removing a muzzle brake then be considered a silencer?
9/17/2014 11:01:08 PM EDT
[#12]
IIRC the device must attach to the firearm. Many shooters use old tires and a wood frame to shoot thru at their home range. It reduces the noise for good neighbor relationhs, however it is not a silencer since it does not attach to the firearm.



I also believe that the ATF says a silencer is any device attached to a firearm that reduces the sound of the report. It never states where the sound is tested, so once again the ATF is allowed to interpret the law as they choose.

No, the definition is a device that attaches to the firearm to reduce the report. You are removing the device not attaching it.

I agree

But the ATF has taken a co to task because the break caused a 2 DB drop, I was looking for the info, maybe someone has it?

Go make an electronic noise cancelling device with no baffles whatsoever and submit it to the ATF.   See what they have to say about whether or not it's a suppressor.

No, it doesn't. Because covering your ears, going inside, walking away doesn't diminish the report of the firearm.

Your second suggestion is impossible, but if it weren't, and it diminished the report of the firearm it could be a silencer.

Shouldn't be considered a suppressor, but ATF clearly has it's head up its ass, so there is that. Just to add fun to the discussion, what if you welded an end cap on it, would the flash hider/brake turn into a silencer part magically?

Is diminished a relative term or an absolute one?

Diminished in relation to what?

How about a firearm that emitted noise in a frequency above or below the range of human hearing?
