After the success of my MP5 and ARP-9 mag adapter, I figured I would make one for the MP7 since there doesn’t seem to be many adapters for it out there right now. This isn’t so much an adapter as it is a spacer which means that little to no bb’s will fall out when you remove the magazine. The way it works is by clicking and locking securely into the speed loader like a normal M4 magazine would. Then you can just insert your MP7 magazine and start loading. The magazine is held in by tension thanks to the size of the spacer. The tension is enough to prevent fall out from shaking, but also to allow for a quick pull to release. You can even store the spacer with your sidewinder as there is a space to fold in the handle as well Tension may vary by magazine. Feel free to sand the side down further for a better fit if you feel the tension is too much Each order will also come with a free “Odin Innovations M12 Sidewinder Mouth Filler Piece” from my profile. The Mouth Filler Piece can also be purchased separately on my profile
