It's an electric flywheel type blaster with a simple gravity fed box clip. The clip has a follower to help feed the darts.
The blaster has a surprising heft and feels incredibly solid. The plastic is very thick and heavy, and ever so slightly pliable in feel, if that makes any sense.
I haven't tried it out yet, but I think this will be able to load and fire stefans/slugs with no modification. The battery compartment was thankfully empty, and completely free of corrosion.
