I have a Proline and mine screws into the Fore-Grip and the piece the sear catches on is threaded as well. That piece has a set screw and I set everything up to "tune" it but my first 5 shots were within 4 FPS, I couldn't bring myself to mess with it.
Started with a Splatmaster, moved onto a Nelspot 007, then came the Autocockers, then "reliability", a STERLING Pump, next was a Bob Long defiant then a PM7. As of now I have 4 Sterling Pumps, 1 Phantom for SC and 2 Spyder's one is a future Spump.
