"for $110 this is by far the best gearbox for the money. i'm shooting between 495fps and 505fps and with a systema magnum motor the rof is amazing. for those of you that think "you get what you pay for" forget it, this gearbox performs just as good if not better than the systema m150 gearbox. and even better if something does break the parts are cheaper to replace. hands down the best gearbox for the money and on the market. i'm very impressed with most matrix products for the plain and simple fact that they are cheap and made with pretty good quality. hope this review helps some of you because sometimes its not how much you pay

"I installed the gearbox this morning and I am sad to announce that it failed horribly. After 300 rnds I noticed it started to sound funny and the fps was dropping significantly. tI opened the gearbox and found that the polycarb piston head shattered into a dozen pieces which in turn destroyed the cylinder head. Upon further inspection, I noticed the switch assembly was very flimsy and was beginning to burn up and melt.

My boss bought the front wiring version of this gearbox and had the same experience.

We are both using 11.1v lipos with 20c discharge. As for this box being lipo ready, I would recommend buying a different box.

On the plus side. I do like the stronger design of the case and the ballbearings, but until Matrix fixes the weak internals I wouldn't recommend this to anyone.

"This Matrix Gear box is the real deal!!! I chrono at 560-590fps, ROF is 22sec, i love it! I also have the matrix magnum motor on it with a cheap all metal JG hop-up unit, with a cheap D-Boys Metal body, and Lipo battery. Total cost of the gun build up is $283. MATRIX's Gearbox and MATRIX's Magnum Motor $155, JG all metal hop-up $8, DBOYs Metal Body $40, DBOYS pistol grip $8, 733CQB outer barrel $12, A&K RIS rails $29, and Systema tight barrel bore $29. This gun build up is better than any stock gun for $400. I highly recommend Matrix's products; high quality, really cheap price. 5***** i am the hardest hitting gun on the team.

"I put this in my jg m16A2 with madbull 60 degree bucking and fish bone with stock motor and stock battery.It was like night & day.Do not know the FPS butt I wold say around 500+with .20 g.BB. Shot .30g still had a little rise to the BBs' but VERY GOOD rang,I wold say 250+,and dead on target.This is better then my type L96.A very good upgrade, A must do.

"really nice gearbox, shoots 527 fps with .2 BB's. The internals are good except the piston breaks easy. even with a polycarbon piston it still breaks. I changed the spring to 130 with polycarbon piston then it shoots smoothly and been using it for a month. 150 spring just messes up the parts. I recommend this gearbox just replace the spring or just get the m120. But the back wire is really short so if u install this on classic army your gonna drill the sling ring.
