Battery Information Video
New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

Upgrade your AEG's fps to 380 to 410fps. It is highly recommended to upgrade plastic bushings and spring guide to metal bushings and spring guide with this product. Also, it would be wise to upgrade plastic pistons to polycarbonate piston; plastic piston heads to duracon piston heads; and standard gears to reinforced steel gears. Finally for best results a battery upgrade is also recommended.

Product Information:
this is a great spring its been in my rifle for a year now and hasnt lost must fps at all. But remember That THIS SHOULD BE ONE OF THE LAST GEARBOX UPGRADES YOU PUT IN. i made the mistake of putting this in first, thinking because i bought a high end rifle that it would take this spring no problem. boy was i wrong, it eventually tore up piston and then i did some reserch and found that i had to replace around 70% of my internal to take this spring. so word of wise, before you by this spring do some research and make sure you gearbox can take this spring

Pros:
great fps
sustains it fps over a long period of time

Cons:
none as long as your gearbox it reinforced
