i think if you add a bit more barrel after the brake it would help lots more, more time for air to start pulling you forward.

and it looks sick 8)

What about this type or brake?



Looks simple enough to machine...I'm not sure how effective it would be tho.

i think thats more of a flash hider.

Flash hiders don't redirect gasses and have a hole larger than the projectile. Flash hiders usually have slots milled out paralel to the barrel... muzzle brakes have slots vertical to the barrel axis.

If you still don't get it... thats a muzzle brake

ahh yea just googled, but the slits on that one look like they go forward

They don't go anywhere... they're just 90° to the barrel.

Look at it from this angle...

yea just after i posted i was thing its probably the angle

The brake you see in my picture is just slid over the barrel. I do plan on extending more barrel out the front than is shown.

Thanks for pointing that out, though.

you don't have nearly enough horsepower to push it.

Horsepower is a unit of power (lol?)...

Have you done any testing with the muzzle brake? If not, when can we expect to hear about some?

dont know if you want to go with machine metal at all but i just have a modified pvc tee on the end of my high power sniper cannon, it goes from ears ringing for hours to tolerable without any ear protection, not sure if your looking for just a reduction in kick like its suppose to work on a real gun, or to reduce volume, but a silencer works by releasing the expel gases slowly, which takes the sharpness out of the total sound, a muzzle break directs the gases sideways as a way to divert in an organized way, instead of randomly, you could also try porting the barrel, this is common for high grade sporting clay shotguns to reduce every last trace of recoil for faster target alignment down slights

I will be modding the other barrel in a day or two. Then I have to arrange time to go to an area to fire it with a heavy slug.

Give me a week. I will have some info for you by then.

:EDIT: I just got off the phone with a friend that has alot of land. Looks like Thursday I will be able to test the brake. I hope to bring both barrels and do back to back testing with and without the brake. The stock barrel is 4 feet long. The barrel with the brake is 4 feet to the first set of brake slots. So, there is the same distance for projectile acceleration on each barrel.

Actually, "Horsepower" as used in my sentence was merely an "expression"..... UGH

This is the muzzle brake used on my 32mm cannon. The exhaust ports are 90 degrees to the barrel centerline. Muzzle brakes work just fine with or without rearward angle.

Thus my (lol?) I wasn't sure if it was a joke or not
It's all good.

I think I saw a video a while back on spudfiles, involving a PVC cannon and a muzzle brake, where the muzzle brake changed the muzzle report from a bang to more of a screech...

From the reading I have done, yes, muzzle brakes reduce recoil with or without rearward angle. However, the rearward angle does more than a 90 degree brake. However, the 90 degree brakes are not as loud IIRC because rearward brakes direct the sound back to you, whereas the 90 degree brakes direct the sound to the sides.

That is a cool looking cannon. I am undecided if I should black out everything on mine to make it look more like a normal firearm, or if I should use some other colors to reduce the chance of someone thinking I have a should launched anti-aircraft weapon.

It's basically action and reaction.

By venting sideways at 90º, the brake is throwing the air out perpendicular to the barrel line, meaning it makes no contribution to proceedings in either direction, and therefore lessens recoil compared to not having porting.

By venting rearwards at an angle, there is a force vector along the barrel line, meaning there is a resultant force actively pulling the barrel fowards meaning it is much more effective at mitigating recoil.

You could also vent upwards, pushing the barrel down and combating muzzle rise, which would be especially helpful given that the line of recoil is well above your shoulder, as opposed to the "straight line" sort of recoil of say the FG42.
