why would you want to use this? to complete the look and feel of the FGC9 (MKII).
if that is not what you are going for the FGC68TMC rail kit will act like a rail riser. when you use the normal buffer tube of the TMC. or you could go and make it lower with the lower buffer tube kit or one of the A5/X7 butt stock adapters that I made

I have modded to strengthen the pin with a M3 bolt
