5D Tactical Jig PRO ReadyMILL End Mill Bit

5D-RMA 1


You must purchase the correct ReadyMILL™ for your router. Your router's model number can be found on the label. If you plan on becoming a true at-home gunsmithing pro, an AR-15 builder with a reputation, you need top-of-the-line tools, and one of the most important tools you can invest in is the 5D Tactical Jig PRO ReadyMILL End Mill Bit.

The 5D Tactical Jig PRO ReadyMill End Mill Bit is one of the industry’s finest 80 lower end mill bits. Made from some of the hardest steel on Earth, the ReadyMILL is precisely forged and cut using the latest CNC machining. A super-heated thermal fit tool holder threads directly into your router for easy setup and milling.

This custom 5/16” end mill is not a “universal” milling bit. Rather, it has been specifically tested and designed for fast, precise 80% lower milling. Because of its unique design, the ReadyMILL End Mill Bit measures just 1.5”. This shortened mill bit requires less torque to mill, resulting in greater cutting power, more precise milling, and reduced tool chatter – a particular benefit when machining forged lowers.

The ReadyMILL is designed to work with the most popular and widely available off-the-shelf routers. Simply select the correct letter under the drop-down option before adding to cart! See the chart below to fit your new ReadyMILL to your router of choice.
