Try using nail tipped cones instead of batteries, they generally fly allot straighter.

i generally don't like ball valves unless they have got a trigger mechanism but i like how you have incorporated the pressure vessel into the stock. keep up the good work.

Have you thought of making a trigger mechanism? If so here is a link to the one i made. it works very well.

Thanks matey.Some people are sceptical if it works or not..Well actually most are but it does work.The main issue is the twist rate,still perfecting that.

Nice to see some people can keep info safe,oh and what do you think of the rifling looks good you reckon?

looks good.

I like how the chamber is intergrated into the stock sorta.
That valve looks awkward to open, if you turned it around, and had the lever pointing up, it would be easier to use, seeing as to open it, you've just got to pull your thumb and first finger together, but thats just me.

Other than that, looks great and seems like it would get the job done.

Cheers.
