This is for a preorder of the M60B Bottle valve that can be used on the Umarex Zelos to convert it to a Bottle Gun. You can add the trigger guard as well to get a pic rail for mounting a bipod, and an aluminum or carbon fiber bottle.
Replaces the original valve that only had the gauge and no fill nipple. The new version has both gauge and male fill fitting.
Pin valves are here and will be installed in the bottle valve.
