M202 Anti-Tank Launcher

[specter]

Iv'e been wanting to do one of these for a while. Basically what I was thinking is something like my launcher, but crammed into a M202-esque shell. So basically it's a single shot launcher with 3 dummy barrels. any thoughts? My only concern is if it will have a functioning trigger or just a ball valve like the one I have. A push button valve would be much better but I cant seem to find one that is adequately pressure rated (mine currently is holding back ~300psi.

nope

Err....why use such a high pressure? You can drop the operating pressure (and achieve the same results) with a larger accumulator. (I shouldn't even be giving help to anti-tankers, but feel compelled to.) Simply enlarge the accumulator until it is roughly 1 to 1.5 times the volume of the barrel. Quality name-brand (Harvel, Carolina, etc.) Schedule 40 PVC is pressure rated to 200-240psi (depending on manufacturer). Avoid DWV PVC, it's not pressure rated.
Once you get your accumulator pressure down to ~60psi (that's what I use on the tank's cannon, btw), a modified sprinkler valve with electric push-button operation (from a 9V battery) or a bleed valve trigger is possible. The M202 shell is more than sizable enough to hide all of the above easily.

For this, I shall spare you
