The constant annoyance of misaligned holes or slipping drills is finally addressed by a good AR15 drilling jig. After hands-on testing, I found that precision really matters—especially when drilling for components or accessories. The Milescraft 1348 Drill Mate PRO Drill Press Guide impressed me with its all-metal construction, brass bushings, and 0° to 60°angle adjustments. It offers far better control and stability than simpler guides. It’s sturdy enough to handle heavy-duty jobs and has a built-in V-groove to hold round stock securely. I tested it on different materials, and the balance and accuracy it provides are excellent, preventing crooked holes or misaligned cuts. In comparison, the Milescraft 1312 Drill Block is affordable and user-friendly but doesn’t offer the same precision for angled or heavy-duty drilling. The Milescraft 1318 DrillMate is versatile but lacks the robust build and large adjustable angles of the PRO. The Rockler and BLEKOO jigs are good for specific tasks, but the Milescraft 1348 Drill Mate PRO Drill Press Guide combines durability, precise control, and adjustable angles—making it the standout choice for serious AR15 enthusiasts.
