Brownells Universal Hammer/Sear Pin Block Kit

The machined steel block facilitates the external alignment of the hammer and sear (or trigger) outside the firearm, providing an unobstructed view of the critical engagement point. It accommodates a wide range of hammer and sear pins, suitable for various handguns and rifles. The dovetailed adjustment block moves within a slotted channel, allowing precise pin spacing adjustments to match specific frames and receivers. An Allen screw secures the pin setting, enabling the hammer and sear to be positioned accurately relative to their actual location in the firearm. This tool is ideal for shaping engagement surfaces on new components or fine-tuning existing factory parts. Each pin is individually numbered for easy identification.
