Editing Air Power (section)

=== Apex and Apex Elite ===

The [[Air Power Apex|Apex]] was introduced during the late 1980s and was listed by the historical equipment database [[VintageRex]] as a 1988 model.

It was a .68-calibre pump-action marker based on the Nelson valve system. The Apex featured direct feeding, constant-air operation and a fixed barrel.[3]

An important feature was its Venturi bolt, developed by Greg Koteski. Rather than delivering the firing gas through a single central opening, the bolt distributed the gas through multiple ports.

The design was intended to reduce paintball breakage when using the comparatively fragile paintballs available during the late 1980s.[1]

Air Power subsequently introduced the [[Air Power Apex Elite|Apex Elite]], which VintageRex dates to 1989.

The principal difference was the Elite's adjustable velocity mechanism. Whereas the original Apex required spring changes to alter its velocity, the Apex Elite incorporated an adjustment screw accessible through the air-source adaptor after removal of the tank.[4]

Air Power adopted computer numerical control (CNC) manufacturing during late 1992.[1]
