The Dead Air Odessa Booster Shims from Dead Air Armament are designed to fine-tune the tension of the booster spring in conjunction with the Odessa piston and Booster spring, enabling precise control over slide cycling on tilting barrel handguns. This set includes two shims that let you experiment with zero, one, or two shims to achieve three distinct spring-tension levels, giving you a simple, effective way to optimize performance for your specific pistol and ammunition. By incrementally adjusting booster tension, you can influence how reliably the slide returns and chambers, potentially improving cycling smoothness and reducing misfeeds or timing issues under varied conditions. Crafted with compatibility and durability in mind, these shims integrate seamlessly with the Odessa system, offering a straightforward upgrade path for shooters seeking consistent, dependable operation. Whether youre refining your setup for precision shooting, varmint hunting, or range days, the Odessa Booster Shims empower you to tailor your firearms cycling dynamics without major changes or extensive tuning. Trust Dead Air Armament to provide a practical enhancement that supports reliable, repeatable performance when it counts.
