Editing Nelspot 007 (section)

== Design ==

The original Nelspot 007 used a manually operated bolt-action mechanism and an in-line valve design subsequently known as the '''Nelson valve'''.

The marker had a fixed barrel and an ammunition tube positioned above it. Paintballs entered the breech by gravity when the bolt was manually opened.[3]

A 12-gram CO2 cartridge was housed inside the grip.

The original marker had the following specifications:[7]

The original Nelson valve used a spring-driven hammer and hollow power tube to release compressed gas behind the paintball.

This operating principle subsequently appeared in numerous purpose-built pump paintball markers.[3]
