I need ideas for slightly larger and way longer barrels than a pen tube... Ideas?

1/4" or 3/8" PVC, brass, steel or aluminum (with the steel or brass they sell long nipples which come in sizes 1" long to 12" long. It's just pipe with 1" of threads on each end and the PVC comes in 36" pieces at the Home Cheapo near me).

1/4" hydraulic tubing! I.D. of .18" and can be used with a simple 1/4" compression nut. Steel is bendable, and aluminum is usually rigid. Make sure before you buy.

I thought that the aluminum was bendable, and the steel is usually rigid...

Either way, I bought the steel, and it works pretty well

I think I'll go with that.

I found some transparent vinyl tube really thick.. I attached it to a water bottle, using some sytrofoam to straighten it out. I should of thought about it.. it burned a bit in the part of the vinyl tubing inside in the bottle

For one that I am currently making I used the long metal part from a charcoal lighter. My favorite part about it is that the end flares out a bit and has slats on the end so it looks like it has a recoil reducer.

Most Plastic Straws are perfect for .22 pellets... Or you could get a real barrel off of an old air rifle, then it's even rifled.

I have a 2000mm long 12.7mm barrel on one of my minis (220ml) It's aluminium two piece with a Acetal coupler. It's hella powerful (can shoot through .8mm sheet metal)

Peace
