Ranger parts and Commando Parts nelson based pumps by Worr Game Products. These WGP parts are compatible with many other nelson pumps and are well made. I like to use these parts on nelson hybrids I put together, especially stock class guns. The ranger bodies can be adapted to work with nelson 007 pumps or to work with carter pumps.
The WGP ranger is a longer snub and the commando is a standard nelson spec snub. Both use a long screw in front for mounting with will need to be removed if you plan on using them with a carter collar. They are not threaded for the front grip frame screw.
Questions please ask.
