ok so does anyone know if i can install an hk51 barrel to any barrel for example taking a g36ke and screwing on the hk51 outter barrel would that work or no? cuz as you can most likely see where im going with this
Assuming that it's a 14mm counter clockwise threads on your G36k, you would need the HK51 outer barrel that would match that. I have one for sale for $40.
