Important Update Regarding ATF Regulations and Pro Jig Sales
Due to recent changes in ATF regulations, 5D Tactical can no longer sell or support jigs directly.

Support and Warranty Service: For all Pro Jig customers, will now handle support. Modulus Arms will honor warranty services, provide technical support, and offer replacement tools and parts for all Pro Jig products.

Manufacturing and Sales: While Pro Jigs will continue to be manufactured by 5D Tactical, all sales must now be conducted through our independent dealers to comply with the new regulation. We are no longer permitted to sell jigs or distribute manuals via our website under these new ATF rules.

Legal Challenges: We are actively challenging this government overreach in court. We are optimistic about a favorable ruling from the Supreme Court in 2024, as both the District Court and the 5th Circuit Court of Appeals have ruled decisively in our favor.

Availability through Dealers: In the meantime, our jigs are still available through our dealers, despite our inability to sell them directly.

We appreciate your understanding and continued support during these changes.

*There is nothing functionally wrong with these jigs, they just have minor cosmetic blemishes. Blemished products are a final sale item. Any functional issues are still covered under our manufacturer warranty.

PRO Jig Tool Kit

  • Fast and Easy - The Multiplatform Router Jig PRO by 5D Tactical is the fastest and easiest universal 80% lower jig on the market today, bar none. In testing, we were able to finish an AR-15 80% lower including jig assembly, in under 15 minutes with excellent results.
  • Incredibly Durable - The first universal 80% lower jig ever to offer all ultra-hardened, heat treated steel wear surfaces. The 1.25 inch thick drill guide is constructed of 100% hardened steel, and the side plates house 1.5 inch ultra-hardened steel drill bushings. If you can wear this jig out, we want to hear from you!
  • 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.
