Barrel holes

Unread postAuthor: THEMOST » Wed Oct 18, 2006 5:02 pm

What is the use of having those fance holes on the end of a barrel? Does it help with the accuracy, speed, or silencing, or something?

ohhh ok. Another thing about silenceing, I'm making a pneumatic rifle that has the barrel inside of the airpressure chamber. The barrel goes through it. Would the compressed air around the barrel help to silence it?

not likely, the bang you hear is from the gas rapidly escaping the barrel all at once, to silence it you have to let the air out slowly, thats what the holes are for... there are more complicated designes but if you look you will find them.

In essence the process of drilling multiple holes near the muzzle is in attempt to replicate a <a href="http://en.wikipedia.org/wiki/Muzzle_break">Muzzle Break</a> on a solid propellent based weapon.

Besides 'looks' the article points out that the device dubbed a 'muzzle break' is used to redirect propellant gasses. So one who might add such a device to ones potato gun might be attempting to achieve one or multiple of the following effects: reduced recoil, flash suppersion, etc.

Is it just me, or does everyone need to spend a little more time on there posting...? [Posting looks like sh*t]
