You guys think stuff is true? Watch the lil vid it has.

I call BS on the claim of 600%. I can see how a brake could increase accuracy, though. I've seen a lot of AKs that have different points of impact at 50 yards with different ammo. Mine quit doing that after I put a good brake on it.

[Firearms4life]

Ok well ill be honest. 600% did seem absurd but according to that video of the shock waves exiting the recess. It does seem to be physically possible to increase accuracy with the device.

It says "as much as 600%". That's the top end improvement you'll see. You could see a minimum of 0% improvement.

The Browning BOSS was/is a muzzle device that allowed you to tune the barrel so that for a particular ammo the barrel vibrations/lash/etc. had the least effect on point of impact. It was a bit fiddly and could come loose in the field, but it actually worked.

Now what this device is claiming is multiple things that are very different from the BOSS and all of the claims are quite unlikely. One of their many claims is that this device will keep groups tight from a cold to a hot barrel. Hm. The reason you end up with shot stringing is that only the highest quality free-floated barrels heat evenly along the whole length. When you heat 99% of gun barrels, every asymmetry in the barrel is a place where the barrel bends as it heats, and each bend moves the muzzle around in a difficult to predict manner.

Sorry. No muzzle device will compensate for that.

It says "as much as 600%". That's the top end improvement you'll see. You could see a minimum of 0% improvement.

The minimum "improvement" is quite a bit worse than "no change".

125$....

I remember when you could get a whole SKS for that price.

[dadoody]

This product has been brought up many times in the past. Basically, it's all bull-crap.

[will227457]

drop 125 and let us know...but if you really want to find accuracy there are better things to spend ur money on....

[trinydex]

i don't see what the shockwave has to do with anything...

those are generic pictures found in ever fluid dynamics engineering book in the first chapter.

[Firearms4life]

Maybe i should call them and ask, according to physics, how it really works.

[Fjold]

They'll tell you that it modulates the pressure impulses to dampen vibration. Which means jack squat.

The real operating principle is that for everyone that gives them $125 they pocket $120 of profit.
