The Elite Builder Jig w/ HSS Tooling
The Elite Builder Jig ditches softer aluminum plates in favor of hardened, anodized steel. This adds considerable weight and stability, providing a precise and rugged gunsmithing station. Drill bushings ensure precise alignment of the hammer, trigger, and safety pin holes, ensuring your LPK installs and works flawlessly on the first round downrange. The center-cut end mill allows for easy plunge-cutting of the fire control cavity with any drill press.
