Here is a great new design magazine for the Stormrider, Chaser, Bandit and CR600W. NOTE! These will obstruct the front sight. You will need to mount a scope or red dot in order to use these.
8 shots in 22 cal, and nice and small, so no high rings needed. No need to stick the first pellet in from the back like the stock mag, these you load all from the front and wind as you go, no winding it up first before adding the pellets. Works great, loads smooth.
The new right side load version loads smoother and works better in my experience.
