Matrix Lipoly Ready 8mm Complete Gearebox Set for M4 / M16 series Airsoft AEG (Tornado Speed) - Wiring to the Front
by Jesse Joe M. Date Added: July 29, 2014
I purchased this with a bunch of other parts from Evike to build a whole gun for the first time by myself. I'd had some other friends show me with ones they had built and I figured it was time I did to get more into parts and how they worked.

I was using it in an Aim ABS receiver, the Matrix Magnum torque motor, 7.4 venom lipo battery with a Madbull Ultimate hop up and Black Python Tight Bore Barrel(233mm).

I used Matrix .20 Tracer BBs inside G&G Highcaps and Elite Force Midcaps.

When I measured with my chrono, I was consistently shooting at about 400-415FPS The rate of fire was around 22rps.

It worked great for a day and night op, I brought it home, stored it in my garage for about 3-4 months, took it out, oiled up my mags and used it to play on my birthday last weekend and noticed I had an odd trigger click issue. If I pulled the trigger back too far, it would click and stop shooting. I was able to work through it by shortening my trigger pull, and eventually I ended up duct taping the trigger so it wouldn't go back too far, until I got it home to look at it.

When I took it out, it was cracked on both sides of the gearbox. Once above where the front of the cylinder and again at about 1/2 inch in front of the trigger.

It worked phenomenally the first time I took it out, but it caused me problems the second. I'm hoping mine was just a fluke.

On the bright side, I do have some awesome internals, the bad side is that I have to buy a new gearbox shell to put them in.
