The Ultradyne Gas Block allows the user to custom tune your gas system to a specific rifle and ammunition combination with 16 different adjustment settings. The Ultradyne Gas Block allows for a smoother, cleaner and cooler shooting cycle which improves performance by leveling the feel of the shot and reducing recoil. This results in quicker, more accurate follow up shots. A perfectly tuned gas system also neutralizes the increased gas pressure created by hot ammo and suppressors which minimizes wear and tear on a rifle and creates less fouling and increases reliability. Made from 416 Stainless Steel with a Black Salt Bath Nitride finish. Designed to be disassembled and cleaning. Machined in the USA.

Bore diameter: .750"
