California PB Supply Top Gun
The California PB Supply Top Gun was a .68-calibre direct-feed pump-action paintball marker. VintageRex dates it to 1988 and describes it as a Nelson-pattern design similar to the Line SI Bushmaster.[1]
The Top Gun had a removable barrel and could use a 12-gram CO₂ cartridge or a constant-air supply. VintageRex describes a quick-stripping system called Fastlock, which used spring-loaded ball retainers in place of screws to hold assemblies together.[1][2]
