If you have built bakenbitz BBKWG
you have probably found that the magazine is too wide and the ram rod sometimes does not hit the blue rods. here is how to fix that.
Step 1: Mod the Mag
pic 1. what the mag looks like before the mods.
pic 2. change it to this, the mag after the mods.
pic 3. build the smaller mag pusher.
Step 2: The Hand Guard
simple but it works. replace the green connector at the top of the handle with a yellow connector and a white rod.
