I own two, and in my opinion they are good pistol bases which have good aftermarket support, It'll work stock fine, the first thing that usually goes is hammer related but that usually occurs if you're very liberal with full auto. I own two AAP's with stock hammer internals are they are still working fine with the majority of the usage on single fire.
One of the main benefits is the fact that there's so many different kits for it, you can make it to almost anything you want. MP7 kits and pistol carbine kits exist, and allows you to customise it to whatever you want.
I love mine and both of mine are still going strong with stock hammer components, but I only use semi-auto. I've upgraded the hop rubber and fitted an h-plate in both of mine and they fling .32s like a dream. I plan on getting the wankergun parts for them soon(ish), but keeping them green gas as I don't like HPA. Probably my go-to sniper sidearm at the moment.
