Wow, a girl getting a guy into pb. That's downright revolutionary.
Angel never made a loader to my knowledge, but at one point they made the Intellifeed that was installed in compatible loaders. Essentially, it was like the gun "told" the hopper when to feed. Something similar exists today with RF chips, a wireless version of the Intellifeed. Pretty unnecessary, though, considering the tech behind loaders is reliable enough. You've got plenty high end loaders to choose from nowadays.
Angel Air tanks were pretty cool, but the huge regulator assemblies on them were wacky. They attached directly to the gun (or drop forward), so no separate asa was used. I'd say just go with a more current tank company with standard tank regs, like Ninja.
Angel had a mask in the works, but could never get it past the testing & approval stage. Sad, really, cuz they looked cool.
At least Angel apparel is still fairly easy to come by. You can get jersey & pants.
