You could use a modified 1/2" tee as a sleeve, and put a capped piece of pipe in the middle of the tee, and fill the capped pipe with marbles so you can use it like a magazine.

Yeah, I have always bilived that if you cant do the reserch yourself and figure it out yourself, then you should not be building it. You can only have respect for this gun if you understand how it works.

Dont ask general "HELP ME" questions, come up with a proper design and run it by us to seee if their are any probloms, this is how you learn.

Dont take this post as a burn, take it as an enlightenment, because that is the only thing I wish to convey. :D

Yeah, maybe just do a quite "idea-sketch", even in mSPaint and put it on so we at least have a vague idea of what you really want. Then we can give "suggestions", not "help me!" :wink:

1/2" doesn't work for marbles.At least not for 90% of the bag.I had to bore out my 1/2" pipe to make them wide enough for marbles.But what does work is dubble bubble gum balls(compliments of dollar tree).They are slightly smaller than marbles.Plus they taste good,edible ammo. :D

Flip thats cool. You could also use copper piping (15mm) for marbles I think. And 3/4 pvc is good for paintballs.[/quote]

1/2" marbles work in 1/2" PVC barrel...
What you described in the first post is very similar to the first pneumatic I built. Check out the link.

try 1/2 inch copper pipe for your barrel.

bring a little chunk of it to miachels to the floral section and take a look at their marbles. there are the 16mm ones and then the 14-15mm ones. buy yoursefl those. they should seem like they would BARELY fit. in fact, some of the marbles in the bag dont fit at all. (ive found the clearish blue ones work the best, youll see what im talking about).....

i used this on the barret 14mm and with muzzle crowning and a scope, i can hit a soda can from 25 feet without even trying.

either that, or build yourself a .177 cal BB sniper, or a 6mm airsoft sniper. i have no experience in these whatsoever but they might be worth a shot.
