ive got this newest .357 big bore challenger it is the standard version has 10rd mag 600cc air cylinder, and really puts out alot of energy. ive added a 360 bipod think its utg and got the emperor moderator which ive took apart and done some stuff with it that makes it even quieter. removed baffles turned 90degrees and reinserted at front of mod, this gives more baffle and leaves a space near the back where there is a hole anyway, reinsert outer mesh and add flat pieces of rubber between outer mesh and outer casing, this makes the metal touching sound go away making a better moderator.
also doing my lead in with barrys bullets copper electroplated slugs, this will make the inside of my barrel shiny copper and even more accutrate than just the lead.(done this decades ago with a sherridan air rifle)
