about a second if you dont know what you are doing... just kidding.

my combustions seem to not work as well after about 6 months or so, my pneumatics, however, seem to last for years. i still have m very first and it is about 2 years old.

it also depends on what its made of. a copper QEV gun will out last a combustion by a few years.

If it's a combustion, (and well-made) there really isnt a reason that it couldn't last forever. Your ignitor will eventually wear out, and your spark gap will get corroded. Keep the uv light away from it and dont use any bad fuels and itll be around for a very long time.

If it's a pneumatic, the only thing you really have to worry about is chamber stress. Rubber gaskets may eventually crack so valves may go bad.

If it's a bbmg, it'll last longer than your income reserved for BBs.

If it's a hybrid, It depends on the materials. It'll probably expire a split second before you do :)

If its a mini, It'll last until the hotglue falls off. Then again, 1700kpa's copper mini will probably be dug up 2000 years from now.


Plastic barrels will all wear down with time.

A well maintained, stored and constructed cannon will last ages.

Something like a cared for copper piston pneumatic could last a lifetime, aside from an occasional valve sealing face change - rubber will slowly degrade.

ya, it depends on what you mean by lifespan, if you mean all the same parts, never changed, it wont last long, but if you mean untill it is so gone you cant repair i it could out last you...

It really depends on the specifics. Like if its a combustion it really depends on the fuel. For example, if you are using starter fluid it will last far less than if you use cleaner and lower temp propane. If it is pneumatic and you stay within the pressure limits for the pipe it should last a very long time. I don't know about hybrids but since they have both high temp and pressure, they might not last as long. Airsoft and bb guns ,if they are using something for a seal that keeps the bb from rolling down the barrel I can see that needing to be replaced on occasion. Hope that helped some! Spud

I know of combustions that have lasted 6 years or more! The only thing that went was the ignition. But thats easy to replace!

also depends what you shot. that can do a number on your barrel. i shoot a lot of molded wax bullets and if has left quite a residue on the inside of my barrel. if its a piston pneumatic make sure you keep the parts lubed

That would be the HD DVD security code (otherwise known as the numbers they tried to ban) for a huge percentage of HD DVD movies that was released across the net a while back, against the will of the authorities.

At the moment, the appropriate authorities are trying to track it down and issue take down notices, but I don't think that's working well.
However, you can theoritically get in a lot of trouble for displaying it on the net...

Don't pass a plastic cannon on to the next generation, plastics degrade with exposure to UV light so unless you've been firing it in pitch darkness it's slowly weakening.

OH MY GOD YOU SAID 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0!

Not 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0!


Nooo! :P

My longest-lasting gun so far was between 3 and 4 years and saw at least 500 shots. It was a cell-core ABS combustion. It started with a chamber fan and two spark gaps using screws, with starter fluid as the primary fuel. I added on board metered propane after a year or two.

As long as the pipe was stored at a reasonably constant room temperature, away from sunlight, a spud gun could last quite a long time... Some types of pipe are more sensitive to UV and corrosion than others, also.

Peace,
Pete Zaria.
