"I bought this to upgrade a boneyard h&k G36c (which is awesome btw). The cylinder, air nozzle and piston are of good quality. The anti-reversal latch is pretty useless, unless you lost your stock anti-reversal latch; I don't see any performance benefit of using the included anti-reversal latch over using a stock one. The tappet plate snapped in half, which really surprised me as I cannot explain any user error leading to its breaking. The hk G36c could not use the bearings but I can use them in a different gearbox. For some reason, one of the teeth on the sector gear broke! Shimming was great, and I have no idea why it broke. I haven't used the spring because it would be much too powerful for a stock gearbox. I was unable to use the spring guide in the hk G36c as it has a quick detach spring guide.
I primarily bought this kit for the cylinder and piston / piston head / cylinder head. I bought the kit when it was on sale for $25. I definitely would not buy it at the full price.
piston head / cylinder head combo is quiet
Cylinder is good for increasing fps
Bearings seem to be of good quality
Piston has metal teeth, seems sturdy
Ball bearing spring guide is good quality
Air nozzle has o ring
Comes with a few extra shims
M130 is too stressful for stock gearboxes
Sector gear tooth broke (maybe a fluke??)
Tappet plate broke
Anti reversal latch is not needed

"They say it's for a G36c, however the K, and the E, which are the two larger models are the exact same gun, only with a barrel extension and foregrip extension. I have a G36E outfitted to a sniper rifle and a G36c and I can swap any parts between them any time I want. This upgrade is actually very good for anyone looking to max out the performance of a G36, C K or E. However he is right on a C you will need something like a PEQ2 kit on the side to power this, which is exactly what I did, and had a custom 9.6v 3300MAh small type made for it. Though, I don't really recommend putting this one into a G36c unless the field you play at allows 450+FPS assault rifles, which I really doubt, otherwise you're looking at probably wanting to put this in a G36E(long type) with a 510mm 6.03mm tight bore barrel and high torque motor, using that with a good hop up bucking you will put some effective rounds very far down range rather quickly. This is a good tune up kit IMO, but for automatics, i would recommend the SP120 kit since that's around the 400FPS limit most places stick to.

"Be careful of this kit--you have to have powerful batteries, a reinforced gearbox, and a strong motor to really use it. The gears are definitely high torque with a low ratio (like first gear in a stickshift car--lots of power but low speed). They have to be that way to work the SP150 spring, but that means you'll have to have lotsa power from your motor and battery to make up for it.

Considering that it's so difficult to fit even a mini battery in the G36C, I find it strange that Guarder would even make a kit like this--if it were an AK or G36K, it should be possible to custom-build a bigger battery powerful enough for this kit, but a G36C?

I ended up just using only the parts I could use. It's a nice kit overall--well made with good components. I wish it had more shims included--at high torques, there can't be any play at all in the gears.
