And thats it for now, ill probaly get some video when i have somewhere better to shoot it, cause im in an apartment right now, with a fire deparment about 100 feet away, i did the first two shots off the back porch. but i got to find a better place to shoot it. Next time i shoot it im probaly gonna try to fill them with like some sort of putty or water. so there heavier.

Pretty standard gun except for 2 things. One: I've never seen flexible pipe used as a meter, I like it. Two, what's the threaded endcap on the propane holder for?

Cool cannon, you could use a needle to fill the tennis balls with water. try useing soda bottles, 20 oz plastic should fit rite in.

hahaha, nice one. my cam sucks it has like no autofocus or anything. i can do a tutorial for my Propane meter if yall would like. and when i ever find a place to shoot it i will film and probaly fill TB with water.

and the only reason i used the endcap on the Propane tank holder for, is cause thats the chamber i choppoed off my old gun, when i found out the propane tank fit perfectly so i cut gun in half.

BTW the guns name is Wilson
