The HAMMER/SEAR BLOCK KIT by BROWNELLS is designed for clear visibility of engagement points when mating the hammer and sear or trigger outside the firearm.
It includes an adjustable block for precise pin spacing to fit various handguns and rifles, with an Allen screw to lock the pin setting.
The kit comes with nine sets of pins for different gun models and is packaged in a see-thru plastic box for easy identification and organization.
