Rob Allen Open Muzzle Tuna Speargun

Following three years of research and development, Rob Allen released a state-of-the-art trigger and grip mechanism called the Vecta. Combining this trigger technology with their top-of-the-line railguns, Rob Allen can’t be beat when it comes to accuracy, durability, and quality.

This Rob Allen open muzzle tuna speargun is unique in that it features an extended rail to support the spear and provide more rigidity to the barrel tube. Featuring the same dimensions as carbon barrels, Rob Allen aluminum barrels will reduce flex and improve accuracy across the board. This Rob Allen open muzzle speargun barrel is manufactured from aircraft-grade aluminum with 1.45mm wall thickness, and the mechanism itself is made from glass-reinforced nylon and features a solid 316 stainless steel sear.
