Shinny copper piston rifle

Unread postAuthor: spudthug » Tue May 15, 2007 2:04 pm

this is my newest pride and joy..wow this thing is fun to shoot.. i always thoguht that my huge piston gun (JME-45) was fun to shoot and this is jsut as fun.. psitons rock! this thing kicks like u wont beleive..(at 300 psi)
it packs a huge punch in a smaller package and sends any thing that fits in my barrel through any other thing u can think of... <---rambling

and now for the pics.. i didn tget to do damage yet and i will get some.. sadly that 300 psi pic was only for one day until i get a big shock pump...
it took me and my cousin 15 minutes of pumping to get to 320 psi with his little dirbike shock pump..oh well it was worth it!

dont forget to look at my other gun!!

thats awesome
its got nice pressure and decent volume
most pneumatics can shoot anything, but if to can shoot anything without residue than thats impressive

that is freaking kooool.

now if i may just say one thing in a matter of safety, please replace the hose clamp, they dont tend to hold up in warmer weather with high pressures

i reckon its a great gun, posibly need barre supports, other than than its great.

nice soldering :D umm, i think the reason no one is posting on this is because at this time, allot of people are at school or sleeping, you will probly get allot more replys latter in the day, cause this is a sweet gun, oh and does that soldering not leak? cause when ever i solder anything, it leaks.

now if i may just say one thing in a matter of safety, please replace the hose clamp, they dont tend to hold up in warmer weather with high pressures

I'm always afraid of my thread getting a lack of post, or dying. it makes you want to post something Just to reset it into the list of recent topics, but I know its not proper forum etiquette so I avoid doing it, many times your its not always because the thread sucks

The chamber and barrel could be a lot closer together, which could make it look a lot better.

However, other than that small appearance issue, it seems like a good cannon.
