Mini LRPL-01

<div align="center">Mini LRPL 01

Here is a cannon which I like to call the mini LRPL-01, it uses the same principle as the much larger and much more powerful original LRPL-01. It uses a piston valve like other cannons exept for the fact that in the 3" tee there is a 1.5" peice of pvc pipe with an elbow on it, this is what the piston pushes up against to seal, thus the barrel is no longer inside of the chamber. This allows more air to be stored at about 60 psi in it.
I think that it possibly has a velocity of about 450 fps with the correct projectile at 60 psi, it uses a 3"x6' chamber with a 1.5"x6' barrel. It also uses a modified sprinkler valve to fire it, to fill the gun with compressed air I used a direct connect fitting that directly (obvously) attaches to the air hose, this allows more air to flow into the gun, thus charging it quicker, I also used a small half inch ball valve to control that flow of air

I think the point of the extra tee is to add a muzzle flash suppressor mock-up.

It functions as a muzzle brake, to reduce recoil. AS to its effectiveness, I'm not sure.

from spudshot: muzzle brake drac, what the hell is a buzzle break?

Please, don't kick up old topics.
Only do so if you have a genuine question, or it is absolutely necessary.
