i had the same problem with pneumatics i didnt want to drag around a compressor so finaly i built my first one and a good pump from a bike shop (a high pressure one) and iv never looked bak they are way better than combustions and never miss fire i recomend making one instead, u can also make it alot slimmer with like a 40mm chamber instead of 2 inch

I'm starting to feel convinced by you guys hehe :lol:
Maybe pneumatic IS better than combustion.
But how do i find a pump?and how much will it cost?
Do you think if i go to the supermarket under the bike sector will i able to find a suitable bike pump that is small and portable?

Combustion has a short spike of pressure upon combustion while pneumatic has a everlast pressure on the pvc pipes which i find rather life-threatening :shock:.

I'll be eternally grateful if someone will to draw out or refer me to a nice design which i build my rifle off. :o

NO PAINTBALL?!?! What kind of God-forsaken country doesn't have paintball? You poor, sad, deprived little man.

Moving on. Pneumatics are entirely superior to combustions in my opinion. More reliable, controllable, and powerful. The only reason I've only built a combustion and not a pneumatic is cause I'm a poor college boy. My next one I plan on making a good pneumatic. And despite your concerns, so long as you properly construct and maintain a pneumatic, it's safer than a combustion as you aren't dealing with flammable materials and open flames.

As long as you use pressure rated pipe, you don't have to worry about it exploding,as long as you observe the pressure limit.
Check a bicke store for a pump, they come in all kinds of sizes.
