Increased size of plunger head and pusher
Reduced size of pusher oring mount - oring would seal well but get stuck or ripped off, new one retains good seal without coming off
Thickened face of plunger head to increase durability
Includes mag release remix files
Designed for the 27x25 metal plunger tube version
If you are still having catching issues you may have overtightened the 2 bolts holding the slide on
Hits 135fps with 7kg retaliator spring and 110mm barrel
