Built from experience. Refined by builders.
The Easy Jig® Gen 4 Multiplatform™ is the result of years of experience designing and manufacturing some of the most popular router jigs in the industry. We took everything builders loved about the previous generations, added feedback from hundreds of customers, and refined every detail to make the Gen 4 our most capable and user-friendly jig yet.
Available with a raw aluminum top plate, this edition delivers the same precision-machined fit and function in a clean, unfinished silver finish. The uncoated aluminum may not feel quite as smooth during use as an anodized surface, but proper lubrication can help reduce friction. When used according to the instructions with the recommended tooling, speeds, and feeds, CNC-like results are guaranteed.
The patented Easy Jig® Gen 4 Multiplatform™ is a truly universal, all-in-one jig designed for AR-15, AR-9, AR-45, and DPMS Gen 1-pattern .308 80% lower receivers. No additional adapter plates are required. Switching between platforms is quick and simple with the adjustable rear buffer plate, giving you the flexibility to build across multiple platforms with one jig.

Important: Raw Aluminum Top Plate
This version includes a raw, uncoated aluminum top plate with a silver finish. Because the surface is not anodized, it may not feel as smooth during use as a coated top plate. Applying suitable lubricant to the contact surfaces can help reduce friction and improve operation.
The top plate is still precision-machined and designed to produce CNC-like results when used properly. Follow all instructions and use the recommended tooling, speeds, feeds, and lubrication.
Important Notes
- Router, tooling kit, and 80% lower receiver are not included.
- Raw aluminum top plate may show minor cosmetic variations, machining marks, or changes in appearance over time.
- Product appearance and color may vary based on availability.
