First off let me say that I recieved my RRA midlength upper with ss bbl and quad rail free float tube last month. Outstanding quality and a quick turn around time. You have a customer for life.
I will be purchasing one of your lower recievers soon and want to install a Magpul stock. I need to purchase a CAR length action spring and a CAR buffer. But which buffer? Your site lists two:
AR0107A 107 - Buffer assembly, CAR $10.50
AR0107AH 107 - Buffer assembly, CAR heavy $20.00
Why two differnt weights and which do need for a midlength that will shoot regular spec ammo?
Thanks for your help and all of the great info I get from your RRA forum.
P.S. Sorry, couldn't help myself with the dancing banana.
