why not just use the RRA block? that's what mine uses and it runs well .

I am getting the 9mm Spikes system this weekend. Could you tell me what buffer you are using? I was told to get a shorter spring.

I am running the Spike's heavy 9mm buffer. I didn't even know you could run a shorter spring and I just use the spring my Spike's lower came with.
