"can this handle a matrix high speed, my stock piston teeth stripped so i bought this?

Webmaster: You meant a "High speed motor"? Yup! But you may want to use a weaker spring as M120 is border line of high speed motor.

"I bought this to upgrade, of course, a Version 7 gearbox for a custom project I'm doing. The base gun was an old CYMA or AGM M14, and some of the parts didn't fit quite right, and required a little dremel work, and it now functions fine. The only REAL problem I had was that the spur gear was too small. It didn't come into contact with the other two gears. This may be because it's meant for G&P or real Tokyo Marui gearboxes. Aside from being stuck with a stock spur gear, this is a quality product.

"Just bought this and put it in my CYMA M14, along with a JBU tightbore and the stock bucking and stock motor. This put the gun up to 425 FPS using TSD .20g bb's, and the best part is that the gun shoots within 5 FPS of each shot, so there is no varying. I am very pleased with the results, however the gearbox takedown of the M14 made it quite the job.
