| I am working on a new 9mm project, RRA SBRed upper. I want to be able to use Uzi, Colt, and Pro mags. Is there a block that will do all of these? |
The type of block that you will need is a colt type block. RRA, Hahn Precision, and Colt make these types of blocks. You would need to use modified uzi mags to function with the block and rifle though. I am getting a Hahn Precision Dedicated 9mm Block for my build from Brownells. It is a more permanent block. Hahn also makes an upper loading and bottom loading block which can be taken out easily. If you are making a permanent 9mm gun, I would go with Hahn Precision. I hear that they make one of the best blocks around, but you can't go wrong with the RRA or Colt block either. I hope the info I gave helps you out. Good Luck and Happy Building!! ~ISherman |
I believe it will work, but the bolt won't hold open as the follower on Uzi mags is different than a Colt mag. |

the Hahn Dedicated 9mm mag block is permanent only if you don't know how to remove the bolt catch roll pin. All it requires to remove it is a punch and a steady hand. I have one, and the only modification I've had to make is to slightly bend the ejector up and to the right to get more contact with the brass during ejection. |
