You mean you want a superb fps? In AEG, you can change the spring to the hardest spring you can have (i.e. M160 or M170). You should have a reinforced gearbox, metal piston & piston head, stainless cylinder, change the gears inside your gearbox to a reinforced one, have a high powered motor, and a good LiPo battery. In GBB, you can have a stronger gas (black gas or red gas). It means you should have metal slide and metal outer barrel. Oh yeah, you should have at least 0.28 or 0.3 gr BBs. Btw, you want to PLAY airsoft or you want to HURT somebody with it? Remember, play safe and fun is our purpose in playing airsoft.
It really depends on the muzzle velocity (FPS), what the power source is (spring, gas, AEG), and what make/model the gun is.
Most definitely not. Airsoft is designed and actually, by law in some areas, for 16+. The responsibility factor and safety factor really make this a more mature sport.
It is not recommended to make airsoft pistols, since they would be ineffective and partially dangerous to make ( eg the spring not secured well and hitting you in the eye), however, most spring airsoft pistol cost around 20 UD which is really cheap. Good spring pistols all come from Tokyo Marui, a renowned Japanese airsoft brand that can be found in many stores and online shops in the US or worldwide.
You don't. But if you really want to you can always try some duct-tape, a can of cisco, pipe cleaners, and some super glue. Good luck.
I would highly recommend that you do not make your own airsoft pellets. They might jam and or brake your gun.
the only real m1s are gas powered but company's make guns like them (echo 1 m14) that are battery powered.
no. Airsoft guns could not possibly shoot that fast.
