Anyone have any success finding accessories for a Citadel Boss 25? Searches have proved futile for the most part.

Want to replace the charging bolt handle with something a little less flimsy than the rubber boot. Anything anyone know of?

Also, have heard that Panzer mags will work. Anyone with experience with these?

Please guys, spare us the "POS" and other opinions. Not everyone wants or can afford Remington or Benelli. This particular gun happens to be adept at sending lead downrange accurately and dependably, at that's the first priority, isn't it?
