[Kos-Mos]

I have owned one.

Don't buy it.

If you really like the look like me, you can replicate it with a G3 SG-1 base and a conversion kit.

First of all, battery space is ridiculous. I completely butchered the insides of the stock to fit a very large 12v battery (10x1.2v, 5000mAh).

Second, the pre-cock system is flawed. In theory, it is a good idea. But in practice, you will find that you need an insane battery to get it going. Plus you get about half the shots that you can get with the same battery in a regular AEG. And sometimes the gun will act weird, like one that have a broken cut-off lever. The gun will pre-cock and fire. Then the next shot it will pre-cock only. Then fire, pre-cock and fire.

The moving bolt is a nice feature, but other than letting everyone where you are, it is not usefull.

The stock body is so flexible that it is almost impossible to keep a good zero on your scope. On mine I removed the stock PSG-1 scope that is garbage and installed a G3 low profile rail mount with a decent scope. The body flex at the mount base and at the fore grip/body joint was so large that I avoided to leave it resting vertical on the stock. The weight of the barrel is too much for it.

It is FRAKING heavy. Heavier than my MG36, and that one is not on the light side.

Parts for replacement or upgrades are nonexistent or insanely priced. That is when you finally manage to get to the mechbox, which require you to remove the barrel group, motor grip and slide/open the receiver even before being able to simply look at the mechbox. The box it self is also a pain. It is an hybrid modular mechbox. The top and bottom parts are held in place with two cross-pins, the lower receiver and the upper receiver. To remove the pins, you have to remove the motor grip and the lower receiver. Good luck routing the wires back in after.

So again, if you like the look of the gun, get a metal-bodied G3 SG-1 and build it from there. Aside from the fire selector, there won't be anything different in the final converted gun.
