Reinforced Gearbox

Ok guys, lets hear what everyone thinks about this one...



As everyone knows, and one has felt ;), I have my CA SPR that I just got. I really love this rifle!! I ended up using it more than my CA M24 today during a game.

I have done a little to the rifle, but nothing major or anything in regards to the gear box. I have stabilized the inner barrel, and am planning on on stabilizing the outer barrel inside of the tube as well. That will be apart of the winter projects that I am going to do.

So this is my question to you guys......

Has anyone got a systema gear box in there rifle, and how does it perform? I am planning on getting this rifle to 500-550 fps, so that would be the gearbox with the M150 spring. I am trying to find if the gears are the high torque, and need to find a motor that will work.

I know there are a few different gear boxes at the moment.
There is the Systema Complete gear box, the Revolution, as well as the Systema Energy.


So here is my question to you guys.......

1. Which one of the above would be the better choice?
2. Which one will last the longest?
3. What type of motor would be needed?
4. Would I be able to use a 7.4 v lipo in them and have no problems?
5. I would obviously use Duttons semi auto only mod to her, so no worries there.

I know the revolution gear box is awesome! I have found it in a few places, but have heard that you need the Systema hop chamber to use it. But the one good thing about it is that it comes with the motor, and a mosfett. Now this is on the high side of range, but I can eat Ra-man noodles for a while to get her bought.



If there are any other gearboxes that you guys can suggest, let me know. I would also like to hear anything you guys can tell me about the Matrix 8mm gearbox. Of course in the same FPS as the systema.


I would like this rifle to be done by spring next year. So I can use the rifle at my large game.


Thanks in advance guys, and I can't wait to see what you guys come up with.

In my last DMR, I ran a Matrix M160 gearbox from Evike. I used a G&P M160 motor as well as an 11.1V lipo, and I was thoroughly impressed with the durability. It chrono'd at 503 FPS with .2s (last checked in the spring, before I sold it) and I used it almost every weekend with .3s and had fantastic results. There were no signs of immense wear and nothing has broken in the half year or so I used it (probably 10K rounds) without falter. I would HIGHLY recommend this gearbox if you plan on using any version 2 gearbox rifle or setup, but then again, I have not used the new Systema complete gearboxes. Hope this was insightful!
