Pre- charged Pneumatic bolt action bb rifle

this is my bb rifle, i have tested it and its around the 300-600 fps range. The last shot i did was at 120psi with a perfect sizes pea.
took a while to make. Click here for more pics

ill have video of it shooting later on today.
so far ive tested it and the most power ful shots and the first 2, the rest are little bit less.

atm the solenoid is opened using a power pack but in the next couple of days i intend on getting a couple of 12v batterys and doing the whole wiring up thing.


comments please, constructive criticism is very helpful

Oh ok... When I first saw it I got the impression that it was much bigger. :lol: like 2' or something around that... Now when I look at the schrader valve in comparison to the end cap i can see how big it would be. :lol:

I think you did a fine job! :)

You used available materials and creativity to build something far from average.

I'll give you the big TWO THUMBS UP!

My only complaint is that you have a big heavy hunk of metal on the end of the barrel that serves no purpose other than to bend your barrel out of shape. Also, WTF is up with that C:B ratio? do you have another valve somewhere that I cant see?
