I don't know if it's information overload Etana, but the early models of the MKII have problems with backward compatibility on several clips/magazines. I own one, I know.

For years it's been an unwritten rule that clips are universally interchangeable with all Nerf clip based blasters. Be it a CS-6 or a CS-35, they should all fit any Nerf clip blaster, as well as many non-Hasbro blasters.

That was universally true right up until the MKII arrived on the scene. The MKII doesn't like CS-18s, and many CS-25s and certain CS-35s. There's a problem with the spacing between the mag well and the handle that prevents many older clips from mating properly with the MKII (which is of course a Retaliator repaint, don't even get me started on that).

Bottom line, there are definitely some issues with the early MKIIs. You shouldn't have a problem with CS-6 and CS-12s borrowed from your CrossBolt. But beyond that, beware. It's hit or miss with the MKII (which of course is a repainted Retaliator, in case I hadn't mentioned that before)
