Alternative Views:

Fast and Easy: Even novice users can expect to be able to finish a lower in as little as 45 minutes.

Universal Compatibility:
Fits all known metal AR-15 and AR-9 80% lowers and most polymer lowers.

5/16" Hybrid End Mill:
Our 5/16" Hybrid End Mill (sold separately) uses a 5/16" diameter shank and cutter, with a 1/4" end for easy installation in common compact routers. The integrated bearing system contained within the Router Adapter Plate helps to support the end mill during use, which reduces end mill flex for fast milling and better finished results.

Optimized For Router Use:
The Original Router Jig makes use of our revolutionary router guide system, so the end mill never touches the jig!

Centered and Parallel Features:
The 80% lower is mounted in the jig by the front pivot, rear takedown and buffer extension ensuring the fire control group pocket is centered with the action.

No-Touch Side Plates
: Our No-Touch Side Plates help in guaranteeing universal fitment.

Less Drilling:
Drill only 2 holes prior to milling!

High-Visibility Milling:
The external router guide system allows for an open area above the 80% lower during milling, for high visibility and easy chip removal.

Super Fast Assembly:
Only 11 total screws are needed to assemble the jig, and it never needs to be completely disassembled!

Integrated Depth Gauge:
The drilling and milling depth gauges are built right into the top plate to help with precision results.

Aluminum Construction: The Side Plates are 5/8" thick aluminum, and the drilling guide is 1" thick. For a more durable solution, consider our Router Jig PRO.
