Yeah, hot glue works great, that’s what I’m using in my coaxial. What kind of gun are you making? I.e. caliber, valve type, although I’ve got a good idea, layout, etc.
Call me "Judge", it's easier to type.

im making a coaxial dart gun ( a variation on this one www.spudfiles.com/forums/viewtopic.php?t=2122&) its gonna be 3/8 barrel by 18" and the chamber is gonna be 1" by 12-13". its going to have 2 sights( design in process) and its going to fire my sooper(hehe i said sooper) awesome darts. un fortunately my dads comp isnt working ( we both have macs, but his is intell and the pc side crashed) so i cant ggdt it, but i used the thing on the internet and it shouls get 200-300 fps. and the piston is piloted by a modded sprinkler.

my master plan is to make 2 of them and sell one to my friend and get enough money to buils a nice rifle using a qev.

however as prof. Amadeus asked isnt the hot glu piston a bit heavy? mine is not going to be super high powered, and i was thinking of an endcap inside of the chamber for a piston.if you have a lighter one ill take it, or if the glue one is light enough...

anyway thanks alot.
