Red's Review of OpticsPlanet Exclusive Maxim Defense Industries RDB Roller Delayed Blowback System

I'm disappointed because I can't use it. They don't tell you anywhere in the description that you have to have the maximum defense, buffer and stock for this thing to work. I will be returning this item and getting the carbine length.
