Airsoft barrel

This area is for the discussion of BB or airsoft sub machine guns, and or other small arms such as pellets. No home made BB or airsoft guns should ever be used in a match where you shoot other people... they are too powerful.

If you want a perfect fit buy a used airsoft barrel.

You can find them in the classifieds of airsoft forums like airsoftretreat.com

A lot of layers swap out their barrels to upgrade their guns, and sell the factory barrels pretty cheap.

1/4" copper works very well, is wide enough to prevent from jamming

That might work.. I would look into the 1/4" though. 6mm id could be a real tight fit. This is it: 8967K22. Its a little expensive but you could try it. You can just get a normal 1/4" male adapter and screw it right into something. I don't know about the metric stuff.

i thought there was a lot of space between the barrell and the bb in 1/4 inch.

The aluminum tubing is .05'' smaller than the copper 1/4'' and is probably cheaper.

I had a question about BB barrels and I thought that I'd post here since it has to do with this topic. I am definitely a noob and I know nothing about building nothing, but I like guns and I like things that go boom, so I built my first pneumatic pretty much reading this forum like a bible.

It came out good so now I want to make a small regular over an under pneumatic, like my first gun, that can fire airsoft BB's.

My question was, does anyone know if teh plastic tubing that Crash Test Dummy recommended from teh plumbign section at Home Depot was safe for a pneumatic barrel?

My other question was if it isn't than does anyone have any suggestions for an airsoft barrel that doesn't require welding, becasue I don't know how

Any input would be appreciated

Respect to all

The plastic tubing that I've been using probably isn't pressure rated, but I don't see any problem using it because it's thick walled and it wouldn't rupture or anything unless you threaded an endcap or something over to keep the air from leaving the barrel. since it's just a barrel and isn't behind your trigger, there shouldn't be too much pressure behind it, because the BBs come out extremely fast.

Edit: gotta love DR's attitide! :D
