say whot? the outer pipe of the airram will be the spot the gun should be mounted on. i didnt include bumbers and spring/rubber band in the drawing, i assume one could make those on a few different ways, depending on the aesthetic needs... so, as soon the pressure behind the projectile begins to bui...

hmmm, a "normal" coaxial has a piston wich travels backwards upon openingen... make that heavy, and you got more recoil.... or the gun needs to be on sliding tracks anyway to get the desired effect... you could use these "rails" as youre airram. make it so that you fit smalled diameter pipe into a l...

i agree with jimmy101.

BUT adding sights is never completely useless. IMHO

surely the ammo and gun arent accurate at all, but making sure you point the thing the same way every time rules out human aiming error a bit...

plus, it simply looks better. :P

err, you can put a spring behind the piston, the equalisation hole is there to prevent what you say.... alternatively you could fill from the pilot side, and make a bumper on the chamberside...

the projectile will always be in front of the pressure, hence the "odd" shape...

why wouldnt it work?
