Editing Perentie Viper (section)

== Design ==

The two actions were positioned with their sears facing inwards. A cam on the trigger operated rollers attached to the sears, firing the barrels in succession. The mechanism could also discharge a single shot.[1]

The completed marker incorporated two 16-inch barrels, stainless-steel receivers, mahogany grips, gold-anodised components, a shoulder stock and a bipod. Each action was supplied by a separate ViewLoader VL2000 hopper.[1]

The Viper used a remote gas supply and was designed primarily for compressed air. Wallis reported that rapid firing caused problems when using carbon dioxide.[1]
