VFC Version 2 ECS Complete Gearbox Set (Model: M120 / Flat Trigger)

"I bought this for my CYMA M16A1, Used the old heavier Cyma follower so i slightly modified it. Its an amazing gearbox shooting right around ~335 FPS with .25g Only problem i had is my one pit the small tiny locking one wont align and go through all of the way but its in there.....most of the way. Its a good gearbox.

"Solid gearbox! I recently installed this gear box for my first "ground-up" M4 build. No regrets spending the money.

"Got this gearbox two times

First time- trigger contacts went off the rails and would onky shoot semi. RMA and received new one

Second- same thing happened with trigger contacts went inside and fixed it, worked fine. Then after 500 bbs MOSFET
Fried our with 11.1v . Will not recommend anything higher than 9.6v with this. Also very picky with any receiver other than VFC
