RRA 40 S&W Upper
I'm building another AR, and I decided to go with a pistol caliber upper. I know Olympic Arms has uppers that use modified full size magazines. I was thinking of going with the RRA upper, but I am having a hard time finding any information on them. Can anyone point me to a review?
I am curious if the Oly mags would work in the RRA.
