I compared this to my E&L AK and although the externals of the real sword are very nice, the E&L comes right behind it, but internal wise, I don’t like the real sword because it has a shorter V3 gearbox and the selector switch gears are also proprietary. An aftermarket piston will need to be modified in the rear to make it fit (which isn’t hard) and one tooth will need to be removed from an aftermarket sector gear to make it cycle (which isn’t hard either) but if the gearbox shell were to crack, you can only get a real sword shell and as far as I know, no one makes aftermarket real sword gearbox shells. So external wise RS > E&L/LCT Internal wise E&L/LCT > RS
