[Silverthorn]

I often read that the Real Sword AKs externals are very tough and sturdy like the real ones. A truck could drive over it and it would survive it seems.

I was wondering more about the internals. Now that people have been using them for a while, what is the verdict on the durability of internal parts (mechbox, hop-up, wiring, ...)?

How easy are they to replace since some parts are proprietary to the real sword AKs?

Thanks!
