Here’s the magazine you’ve been waiting for! 12 shots, with numbered indexing to keep track of how many shots you have left. Sticks up over the breech 16mm so standard 21mm Hi rings easily work with it and 18mm rings will work as well.
These mags were designed for the PP750 but also load fine with the Chaser, Stormrider, CR600W, and Bandit. However the breech on those guns is in slightly a different spot and so the mag does not line up exactly. Further testing will have to be done to see if this causes clipping of pellets when loading.
