Real-World Testing: Putting JK Armament 155 MST Precision Drill Jig Kit to the Test

First Use Experience

My first project using the JK Armament 155 MST Precision Drill Jig Kit involved modifying a batch of AR-15 lower receivers to accept an ambidextrous magazine release. This required drilling precise holes in the receiver walls, a task where even a slight deviation can render the receiver unusable. Using the appropriate drill bit and lubrication, the process was surprisingly smooth. The hardened steel jig guided the drill bit precisely where it needed to go.

The test was conducted in my workshop, under normal temperature and humidity conditions. The only variable was the metal hardness. Ease of use was immediate; the jig clamped securely to the receiver, and the drill bit aligned perfectly every time. I encountered no issues or surprises during the initial use.

Extended Use & Reliability

After several weeks of use on various projects, including drilling holes for sling mounts and modifying buffer tubes, the JK Armament 155 MST Precision Drill Jig Kit continues to perform flawlessly. There are no noticeable signs of wear and tear on the hardened steel jig, even after repeated use with high-speed steel drill bits.

Maintenance is straightforward; a quick wipe down with a dry cloth after use is all that’s needed to remove any metal shavings. Compared to my previous experiences with less precise jigs, the JK Armament kit significantly improves accuracy and reduces the risk of errors. It definitely outperforms my older jigs in terms of precision, durability, and ease of use.
