Here is a neat look at the roots of what the Montneel Z1 semi automatic evolved from. This pump was named the J-Mark and was a collaboration between Marcus Neely and Jim Masse. Supposedly Neely and Masse produced 15 of these bore drop pump models in 1989 before moving to a double action named the J-Mark 2. Marcus and Jim eventually split ways and Marcus linked up with Moe Dumont (sp?) and the two went on you build the semi automatic Montneel Z1 markers. During this time Marcus would have been playing on the Beast of the East team and Gang Green.
In this poorly filmed video I look at the safety assembly and how it compares to a Line SI. It’s essentially a direct copy. I also talk about compatibility between other models. The internals are standard bore drop (bolt, hammer and valve) but the back bottle is proprietary and then barrel may be a standard Line SI slip fit.
This pump uses the same flat edged body and slip fit barrels that would make their way to the various Montneel pump models in the future.
Thanks to Ralph “RJ” Torrell and Bryan “BigOldSkool” Keker for helping me acquire this J-Mark which formally say at the EMR paintball museum.
