Rob Allen Moana Open Muzzle Railgun

Overview

The Rob Allen Moana Open Muzzle Railgun is a rear-handle, band-powered speargun for general spearfishing, including close-range hole hunting. It combines an aluminum rail-barrel platform with the Vecta handle and trigger system and a low-profile open muzzle.

Rail design and function

The rail is integrated into the barrel and supports the shaft along its path into the muzzle. The rail also contributes to barrel stiffness, helping limit flex while keeping the shaft supported and level before release.

Power setup

The standard twin-band setup can be reduced to a single band when less power is preferred for close-range shots in caves, holes, or other confined hunting situations.

Care and handling

After saltwater use, rinse the speargun thoroughly with fresh water. Inspect the bands regularly for cracking, softening, abrasion, cuts, or other deterioration and replace worn bands before further use. Disarm the speargun before leaving the water.
