Usage and Benefits

The Universal Drill Press Jig guides the exact locations for drilling hammer, trigger pin holes, safety selector detents and mills fire control cavities, trigger pockets, and buffer tube areas. The replaceable plates mean wear-prone areas can be easily refreshed, greatly extending the tool’s service life.
