The most common mods are:
Buying a higher voltage for higher firing rates.
Buying a stronger gearbox, to keep up with a battery.
Buying a barrel extension (mock silencer).
Some easy, if not as useful mods are:
Painting camouflage on the gun.
Putting frictional tape on the grips.
Adding aftermarket rail accessories, like lasers, flashlights, scopes or handgrips.

Airsoft Megastore 7.00$ -Jeff
Yes
I don't no about spring, but the Green Gas M700 Sniper Rifle Competition Professional Airsoft gun, has 720-FPS!!!! And the, Spring CSI L96 Bolt Action Airsoft Sniper Rifle, has 550-FPS. They are both from, Hobby Tron.com
The Well MB03 Spring Airsoft Rifle measures approximately 38" long.
go for the m14, unless its cheap looking.
if it is electric, or gas, yes. if its spring, its not.
Yes you have to every time. It depends on the spring tension.
Not sure what the question is, be more specific, each gun has its own magazines, and spring guns suck if not bolt action rifles or shotguns.
airsplat.com's Well l96 spring rifle is the gun of my choosing
Best left to a gunsmith
No, it is not. All spring powered guns need to be cocked for each shot.
