Rob Allen Tuna Pro Railgun 100-140cm

Rob Allen Tuna Pro Railgun 100–140 cm

The Rob Allen Tuna Pro Railgun pairs a blue camouflage aluminium barrel with two 16 mm rubbers and a 7.5 mm spring-steel shaft. Its open muzzle, integrated shaft rail and Vecta2 handle make it a practical choice for reef and pelagic spearfishing. Choose from 100, 110, 120, 130 and 140 cm barrel lengths to suit your diving conditions.

Aluminium rail barrel with blue camouflage

The aircraft-grade aluminium barrel has an integrated rail to support the shaft and a 1.45 mm wall thickness. A blue camouflage wrap gives the Tuna Pro its distinctive finish. The low-profile open muzzle keeps the sight line clear and allows the rubbers to be replaced without tools.

Twin 16 mm rubbers and a 7.5 mm shaft

Two Rob Allen blue-over-amber latex rubbers are fitted with Dyneema bridles. The 7.5 mm shaft is made from oil-quenched carbon-alloy spring steel and has two smooth loading notches, a tri-cut tip and a heavy-duty stainless-steel barb. Its zinc-treated surface helps protect against corrosion, while a smoothed shooting-line attachment hole reduces wear on the line.

Vecta2 handle and supplied rigging

The Vecta2 handle combines a soft, textured grip with a stainless-steel line release that operates from the sear. An ergonomic loading butt provides a broad contact point when loading. Abrasion-resistant black 400 lb monofilament shooting line connects to a gun bungee and swivel clip, making shaft removal and re-rigging more convenient. A reel bracket is fitted as standard.

Care after each dive

Rinse the unloaded speargun in fresh water after use, including the trigger mechanism, muzzle, bungee and line release. Dry the shaft before storage and keep the gun out of direct sunlight and heat. Inspect the rubbers, Dyneema bridles, shooting line, crimps and shaft for wear before your next dive.
