The Rob Allen Tuna Pro Railgun is the heavier conventional aluminium twin-band platform in this range. Its open muzzle, two 16 mm rubbers and 7.5 mm double-notch shaft set it above the lighter-shaft Moana and Sparid configurations while keeping an aluminium blue-camo rail barrel.

The available range covers 100 through 140 cm, with the same mechanism and no included reel across all five lengths.

Product overview

About This Product

The Rob Allen Tuna Pro Railgun is the heavier conventional aluminium twin-band platform in this range. Its open muzzle, two 16 mm rubbers and 7.5 mm double-notch shaft set it above the lighter-shaft Moana and Sparid configurations while keeping an aluminium blue-camo rail barrel.

The available range covers 100 through 140 cm, with the same mechanism and no included reel across all five lengths.

Choose 100, 110, 120, 130 or 140 cm based on overall length, loading comfort and transport. The twin 16 mm bands, 7.5 mm shaft and open muzzle remain consistent across the range.

Compare Tuna Pro with Samburu when deciding between aluminium and carbon conventional construction. Moana and Sparid use lighter 7 mm shafts and twin 14 mm band systems.

Heavier than the twin-14 mm families

Aluminium rather than carbon

Tuna Pro is the conventional aluminium counterpart when comparing it with Samburu.

Five consistent length choices

Every length from 100 to 140 cm retains the same core band, shaft and muzzle package.

Reel brackets do not mean reel included

Mounting provision is present, but the supplied equipment does not include a reel.
