Umarex T4E Universal Quick Piercing Bottom Cap Screw Assembly - Gen 2

This is the newest, upgraded version.   It can be used as a replacement for newer models that come with this one already, and it can also be used to upgrade older models.  This works with all current and previous T4E markers that use the lower grip CO2 piercing cap. This new Gen 2 cap features a quarter-turn pressure release mechanism as well as a better grip profile, making it easier to use.

T4E TR50

T4E HDR68
T4E HDS
T4E TR68
