  • Revolutionary Router Guide System - The Router Adapter is used in conjunction with the included guide pins to trace guides of the fire control group pocket, ensuring the end mill never touches the jig. Ultra-Durable glass-filled nylon increases longevity over traditional plates prone to dings.
  • Truly Universal 80% AR-15 Lower Receiver Compatibility -Guaranteed. An 80% lower mounts in our jig by the same locations used to mount an upper receiver. Universal for any AR-15, AR-9, AR-45, .308 or AR-10 lower receiver on the market. Optimized for any material; 6061-T6, 7075-T6, Polymer, etc.
  • Centered and Aligned Finished Features - Mounting an 80% lower by the front takedown and end plate position on buffer tube extension ensures properly aligned finished features, without any additional locating pins.
  • ReadyMILLTM - Our Patent Pending ReadyMILL(Sold Separately), is the strongest and most rigid router based milling tool available today. Nothing on earth comes close! The ReadyMILL™ contributes to the Router Jig PRO producing the best finished results, in less time than ever before.
  • 1.5" Thick No-Touch Side Plates - Our innovative no-touch design, first pioneered by 5D Tactical, ensures universal fitment and less chance for accidental damage to the receiver. The 1.5" thick side plates are double the thickness of the nearest competitor, which will aid in producing perfect selector and pin holes every time, even with a handheld drill.
  • Less Drilling - Only 1 hole needs to be drilled prior to milling!
  • 3-Step Process - Each milling step and depth gauge corresponds to a simple 1-2-3 process.
  • High-Visibility Milling - External milling templates provide open area above the lower for full visibility during milling.
  • Integrated Vacuum Attachment - Our buffer adapter mounting point doubles as a 1.25" vacuum hose attachment which will aid in chip removal while you mill.
  • Super Fast Assembly - Only 14 Phillips screws are needed to assemble the entire universal 80% lower jig, and it never needs to be completely disassembled, even while switching between platforms.
  • Integrated Depth Gauge - The high visibility laser marked depth gauge is integrated to the top plate to keep both hands free for setting drilling and milling depths.
