i am building my first 9mm AR and am using an ACE Ultralite A2 length stock. I purchased the RRA buffer and spaces, my question is what spring do i use, should i use a standard A2 spring or something different. thanks

I used the standard A2 spring. No problems. Didn't know there is one specially made for the 9mm
