Real Steel Information
The Magpul FMG was inspired by the earlier Ares FMG. The Ares FMG was based on a Mac-10 where the Magpul FMG is based off Glock internals.
Ares FMG – Seen in Robocop
Magpul PTS and KWA worked together to build a complete FPG. The Original FPG kit was built to use a KSC or KWA Glock 18c for its’ internal parts, so the partnership was a natural match.
The complete FPG comes with an extended outer and inner barrel which were not available for people who purchased the FPG Kit. It comes with the low profile selector switch and magazine floor plate installed, and includes a 49 round long magazine.
Same performance as a KSC/KWA Glock 18c with slightly higher FPS due to the longer inner barrel.
