Every gun can break. They are mechanical devices and as long as there is friction and electrical resistance, things of all types will break. That's a certainty. But when guys have reported 200,000+ rounds at 400 fps with only minimal maintenance, well that's a different story. There is no engineered AEG out there with that kind of durability. One guy here or there may get lucky with alot of rounds through a gun, but as a general rule, those levels of durability aren't seen in any other guns.
That being said, the SCKs are a whole different story. Guys buy them because they want custom trades, want to save a couple of bucks or want the challenge of self-assembly. Well, all manner of problems happen. It became so bad in places like Europe and the U.S., that retailers refused to sell the kits as they had so much trouble with assembly issues. It has become better now that they provide major component pre-assembly in the kits, but there still is risk, especially for the first-time builder.
Systema does not use a CNC'd 7071 aluminum body like what's found on the real gun. That would violate Japanese law and likely we would have an issue with that as well, considering the uppers are quite close in specs and size. The lower is a bit different to accomodate the motor mount as well. Now, considering the body is a cast alloy, it's as susceptable to breakage as another cast alloy body. But you can buy a real upper and do some small mods to make it fit a PTW.
The gearbox shell is CNC'd steel. The cylinder is made from extruded and machined aluminum. All the gear teeth are hardened steel (MAX only). The only maintenance is cleaning the barrel and hop-up (like any other gun) and replacing the nozzle o-ring and piston head o-ring periodically. This take all of about 10 minutes per cylinder with no gearbox disassembly required.
