As an owner of pre-ban AKs in the US, and have played with select fire versions overseas, you still have a basic standardized system which is robust and simple. I would hope that if the piston system AR has a future, there would be a standardized system as well. A system that is easy to maintain.
I have noticed that both LMT and LWRC have their own rail system installed. Can most rail systems (i.e. KAC RAS) work as well or are there clearance problems with the height of the piston not found with the gas tube?
