This is a pathetic little gun which i made in like 10 minutes using a soap dispenser as the valve you just sand the bottom of it attach the pump then pump it up and fire. It's extremly ghetto but the valve opens suprisingly fast (faster than a blowgun) i reckon at 30psi (thats as much as i can pump it up with this rubbish hand pump) it will shoots a .12g airsoft BB at around 200 fps.

I have know changed it, its inline and it has a much longer barrel so the velocity goes up around 60fps. It's pretty fun to mess around with and i haven't seen any other use of this valve exept for my other one :wink:

Overall it's a pretty good gun and very simple (2 parts)

:)

Its dosent have all the tape on now and its much neater.

This is the soap dispenser that i used. Only some types work others just let the air flow through. Also it has a check valve so you can disconect the pump but they dont last long because of the pressure.
Constructive critisism welcome :)

You could sleeve it in a piece of aluminum pipe and fill with epoxy, as long as you ensure the other parts are up to it you could get fair performance.

A manual XRV would definitely improve performance..

Good point although in the UK it is quite hard to find cheap allu pipe so ill see if copper fits and i'll add a schrader.

yeah but this is for lazy people who cant get off their arse :D But seriously it's an allright alternative if you cant find the parts. BTW im not lazy i just cant get the parts. England sucks for spudgun parts. :x

Also i think its around 300fps not 260fps ill see if i can get a vid.

So double your chances! Go for broke. Unless you can't have two entries.

I apologise, i have read and understand the forum rules but this was is the “new messages” section. Must have been a glitch.
