Description
The Rob Allen Tuna is a rail gun, a speargun whose spear runs along a rail on the barrel, set up with double 16mm bands and a 7.5mm steel spear for heavier work than the lighter models in the range. The barrel is aviation grade aluminium, 1mm thick, and the mechanism is moulded from glass reinforced nylon. It is rigged with single wrapped heavy duty shooting mono, 2mm thick with a 400 lb, about 180 kg, breaking strain, and it carries a low profile muzzle. The gun is offered in 100, 110 and 120cm lengths, so the length can be chosen to suit the hunting conditions.
