"Best Gearbox for the price! Shot faster than a friend's $300 upgraded gun!

Very powerful
Shoots far
Shoots fast
Full Metal
Lipo Ready

Spring so powerful my 9.6 butterfly couldn't pull the spring.
(had to get a lipo anyways)

Notes: At first this gearbox did not fit in my elite force cqb if that's the problem do some shavings on the inside of you lower receiver. If you have trouble just take it to your local shop or field. I run an 11.1 lipo in this and it works great! Happy Airsofting!
