Rob Allen aluminum railguns have the same dimension as the carbon barrels. The extended “rail” incorporated into the aluminum barrel supports the spear the full length of the barrel on into the muzzle. The Rail level lines up with the profile of the mechanism and the muzzle. The integral rail is part of the barrel, thus increasing stiffness and reducing flex. This makes the guns deadly accurate.
The rail barrel is manufactured from aircraft grade aluminum with a wall thickness of 1.45mm. The mechanism is manufactured from glass reinforced nylon and also has a solid 316 stainless steel sear. The Rob Allen Tun Railgun comes with either the Rob Allen Low Profile Open or Closed muzzle which is smaller in profile than conventional muzzles providing less drag and greater maneuverability.

Rob Allen Vecta Aluminum Railguns are available in lengths from 70 cm to 140 cm,  and come with either the Rob Allen Low Profile Open or Closed Muzzle.

Please note that Freediving and spearfishing are inherently dangerous sports and should only be undertaken by experienced, well-trained divers. More powerful spearguns must be fired with two hands and a locked elbow to prevent injury from excess recoil. Do not load or unload your speargun out of the water, treat every speargun as if it were loaded. Never point your speargun at anything you do not intend to shoot. Before you begin your dive, be sure to check all your gear. You should never dive alone and your equipment should be serviced regularly. You should always plan your dive and dive your plan. You should discuss safety precautions, your plan, and contingency plans with everyone onboard BEFORE you dive. Communication among divers and operators is imperative. Failure to adhere to these guidelines could potentially result in physical harm or death.  Blue Tuna Spearfishing is not responsible for any loss, damage, harm, or death caused by using any of our products.
