The Brownells MAGNA‑TIP Ruger Clamp Screw Bit is a purpose‑built gunsmithing bit engineered to deliver a precise, no‑slip fit for Ruger clamp screws. With a 0.43" diameter and 0.83" thickness, this bit is custom‑ground to maximize surface contact within the screw slot, reducing the risk of cam‑out and preventing damage to both the screw head and the firearm. Like all MAGNA‑TIP bits, it’s crafted for durability, consistent engagement, and smooth operation during installation or removal of windage and clamp‑style fasteners. This makes it a reliable choice for anyone maintaining Ruger rifles or working with scope rings and bases that use similar clamp screws.
