Rob Allen Open Muzzle

Product Description

Rob Allen glass reinforced nylon muzzles are designed so that the primary band exerts its force along a line slightly below the rail, holding the spear in the rail on firing. The band is fitted by slipping it into the retaining grips when it is stretched. The secondary band in the double muzzle pulls from a hole lower in the muzzle, thereby reducing barrel flex. The secondary rubber must be retied or alternatively a “Quickie” wishbone can be used.

A clear line of sight on Rob Allen open muzzles makes aiming much easier and far more accurate. This muzzle is significantly smaller in profile than conventional muzzles which makes it easier to maneuver as the drag has been dramatically reduced. Divers are able to view and track fast moving fish with ease.

Spears are securely held in the open muzzle by the line, even when mono nylon is used. Spear line can be led left or right over the open muzzle ensuring comfort for both left and right handed divers. Spears are much easier and quicker to load than conventional muzzles as they do not have to be threaded through an eye on the muzzle.

The entire muzzle is constructed from 30% glass reinforced nylon with an internal spigot and outer skirt for additional strength. The skirt also reduces stress concentration when fitted to carbon barrels.
