The Evolution Threaded Rod with Notches is made by Sigal Sub using the best quality Swedish Sandvik steel, heat-treated to increase its mechanical characteristics. It is a sturdy, rigid and very precise rod, perfect for closed and open-headed arbalete rifles. The two new-generation hookup notches are not simply milled as is usually done, but are machined using a special technique that allows for the creation of a rounded-profile seat, free of sharp edges and corners. Evolution's notches thus allow the use of dyneema ogive, without the risks of them being damaged or breaking quickly. Sigal Sub in this model features the rod in a threaded configuration to allow the use of spear and harpoon. Available in 2 different diameters: 6.5 mm, 7.0 mm. Available in multiple lengths: from 50 to 115 cm. M7 (7 mm) thread. Read more
