Rob Allen 900 GT Carbon Roller gun


The Rob Allen Carbon 900 Rollergun.


This new technology adds 2m plus onto the range you would have with a traditional gun of the same length. By pre tensioning the rubbers and running on ceramic ball bearings in rollers on the muzzle, this gun is able to give you exponentially more power with little to no recoil.

Rob Allen has spent over 2 years trialing and engineering this high-powered roller gun to bring to the spearfishing world a roller muzzle that performs with perfect accuracy, high durability, and incredible power every time you pull the trigger. Like all Rob Allen products, it has been designed and built featuring large rollers and ceramic bearings. These new features have proven to give incredible power, efficiency and improve accuracy whilst remaining consistent with the stereotypical, hard-wearing craftsmanship of Rob Allen.

This new speargun offers minimal recoil with maximum power to take a huge range of fish. The muzzles unique line guide system ensures effortless reloading, combined with stainless steel anchor points at the handle providing full band extension and the utmost accuracy. The quality of the Rob Allen Roller Muzzle is guaranteed.

1.45mm thick Aircraft grade Aluminium Railed Barrel.

Next generation Vector 2 handle with mechanism.

Low Profile Closed muzzle.

Green Grip. – Green Muzzle Bungee.

7.0mm Double Notch Oil drenched carbon alloy spring spear.

4″ Shark Clip.

High strength, abrasion resistant black 180kg shooting line.

Vectra 2 Mechanism.

The Rob Allen Vecta Mechanism is moulded from PA6 30% GS glass filled Polyamide to handle the power needed to hunt large blue water fish.

External shrouds and an internal barrel spigot increase strength at the critical barrel/mechanism interface. Apart from safety considerations, any flex in this area reduces accuracy.

Internal webs at several places in the mechanism are designed to spread loading away from high stress areas. All load bearing pivot pins as well as the spear are manufactured from solid stainless steel.

The rubber overgrip is clamped in place by the cheekplates to prevent twist on firing. The spring loaded line release cam returns to position after firing for ease of loading.

The Snapper comes with a 7mm double notched shaft with a 40cm overhang (the difference between length of barrel and length of shaft).

The spear is attached to the muzzle via a single wrap of 2mm monofilament and a 10cm gun bungee.

The Snapper comes fitted with twin 14mm rubbers with dyneema wishbones.
