Homemade Mini Coaxial Airgun

Step 3 The barrel

Well you are going to need to epoxy the barrel to a 1/4in brass nipple in orded to attatch it to the gun.

I recommend you click on high quality at the bottom.

Next I would reccomend you clamp it in a vice for an hour or so but if you don have a vice then you are going to have to just hold it in your hand steady for about 20min and then set it down for another hour or so.
After that hour wait for it to partially dry you can screw it into the 1/2in to 1/4in bushing on that 3/4in female adaptor you put aside. Remember to teflon tape it.
