.40 Cal

<div align="center">.40 Cal

Provided By - dmt4595

I have my version of robbie's .40 cal gun almost finished and working. I still need to make the stock, and i still need to find a good schrader valve - the one i have is from a bike tire epoxied in - it works fine, but the pressure guage has a pinhole leak. I also need to finish modding my sprinkler valve - it works fine, but i forget how to make it work without leaving the solenoid screwed in - something about epoxy in the holes, but i dont remember which holes to fill lol. I should have pictures up in a little bit if my brother is nice to me.

I also went out and bought a 4' long steel rod today at lowes to use as a ram rod... i just found out that the tail of the metal tipped stun darts is a perfect fit for the rod, so naturally i made some darts. (the rod was 1/8" steel welding rod) right now i only have 2, i dont want to waste too many of the stun darts that i bought, so until i buy some more tails for them, i will only have maybe 5 hunting darts tops. (and when i say hunting, i dont mean i am going to shoot them at living things - im not that stupid) i tested one of the darts out at a cardboard box filled with old magazines at 25 psi - went through 4 and the tip was lodged in the 5th - with plenty of shaft not even into the first magazine yet.

Thats awsome. You could go can hunting with those darts. Set some cans up on a raling, and snipe em. Real sweat ammo. Shouldn't the barrel be longer?
Real nice

nah, I think that the barrel is fine a length as it is right now, I really reallly like the fact that you stuck the barrel into the tee leg, this allows the barrel to be pressed against the chamber making a better cleaner look.

I like the style. Very nice! Do you happen to have ann0ying stray cats around? jus jk. Pretty cool darts where did you get them? Cabelas? I plan on making a sniper kinda like that but the stock will be different.

I don't know the acctual cost, but here's an approximation:

7$ - pvc fittings
12-25$ - sprinkler valve (matters whether you buy them from joel)
5$ - chunk of pipe
6$ - blowgun
7$ - miscillaneous parts needed for pnematic modification
5-10$ - pressure gauge
10$ - barrel

Thus; 77-95$.

Thats probably a 72" .40 cal blowgun, without the mouthpiece shoved into it.
