Fast and Easy: Even novice users can expect to be able to finish a lower in 45 minutes. Advanced users can finish a lower in as little as 30 minutes! The AR-15 Router Jig is by far the fastest and easiest router based AR-15 jig on the market, bar none!

Universal Compatibility: The Router Jig is truly universal for all AR-15 80% Lower Receivers. A lower receiver is mounted and located in the jig by features which are standardized and common to all AR-15 lowers; the front takedown, rear takedown, and buffer support. In other words, our jig mounts an 80% lower the same way an upper receiver will mount when the lower is finished. By using these known standardized features to mount the lower, and in conjunction with our No-Touch Side Plates, we can guarantee universal fitment for any metal AR-15 lower receiver regardless of exterior dimensions. Our jig will also fit most metal AR-9 style lower receivers. Many other jig designs make use of non-standardized features or rely upon clamping the lower into the jig by the sides. The result of other mounting methods is non-universal fitment and the opportunity for out of spec finishes. By mounting the lower receiver in our jig by standardized features, an additional benefit is the most accurate finished product possible. In order to guarantee proper fitment and operation, all finished features must be aligned, centered and parallel with the components for which they are designed to receive, in this case the upper receiver and lower parts kit.

Optimized For Router Use: By far the most popular method for completing 80% lower receivers at home is by use of a handheld router. This is for good reason, of course, because it's the most cost-effective and readily available method, and finished results can rival those of an expensive CNC machine or mini-mill. Our Universal Router Adapter addresses certain drawbacks previously associated with using a woodworking router to mill aluminum. First, for the main milling operation, all other router jigs rely upon "tracing" an internal FCG pocket shaped template by running the end mill shank against a template surface. This method generates excessive heat, excessive wear on the template surface its self, and the end mill is not supported in all directions for the milling operation. Our Universal Router Adapter incorporates two main features which reduce or eliminate any drawbacks to utilizing a compact router for milling aluminum. First, the Adapter houses a high-speed bearing which assists in centering the Adapter to the router, and supports the end mill in all directions at all times, greatly reducing tool chatter during the entire milling operation. Second, the Adapter accepts 3 sets of Guide Pins, corresponding with each of the 3-step milling process, which are utilized to trace two external cavities. The external guide cavities with Guide Pins completely eliminate the need for an internal template coming in contact with the end mill.

Oversized 3-Flute Hybrid End Mill:
Our Patent Pending reduced-shank end mill is an industry first, and an absolute game changer in the realm of router based 80% lower receiver milling. We identified the end mill tool as a weak link in many existing router based jig designs, and addressed the drawbacks with a fresh outlook. Two of the limiting factors related to the end mill tool are the router collet size, and necessary minimum length for the application. Other router based jigs utilize an unsupported, 4" long, 1/4" diameter end mill which cannot produce high quality finished results. An end mill with this length to diameter ratio is not nearly rigid enough. The effect of this is unwanted tool chatter, frequent tool breakage, unsettling feedback, slow milling operations, and poor finish quality. To solve this, we increased the diameter of our end mill to 5/16" resulting in a 4x stiffer shank. Our oversized 3-flute Hybrid End Mill transitions to a 1/4" diameter to be compatible with standard compact routers. Our end mill is exponentially stronger and more rigid than a 1/4" diameter end mill of similar material construction and length. Milling your 80% lower receiver is now a fast and smooth process.

Centered and Parallel Features: Using the buffer support, front takedown and rear takedown to mount and locate the lower receiver in the jig guarantees the finished fire control group pocket, trigger slot, safety selector, and trigger/hammer pins will be perfectly located and within tolerance. This ensures proper fitment and trouble free operation once the lower has been completed and assembled to an upper. As the sides of the AR-15 lower receiver are not controlled or consistent, using them as a means of mounting the lower into a jig can result in a misaligned fire control group pocket and trigger slot, misaligned safety selector holes, or misaligned hammer and trigger pin holes.

No-Touch Side Plates: Our industry first No-Touch Side Plates provide ample clearance on either side of the lower receiver to accommodate for even the most wildly out of spec designer brand lower receivers with oversized exterior features and AR-9 80% Lowers. This no-touch approach prevents accidental damage or marring to the side of the lower receiver during assembly, use, and disassembly. As an added bonus, since the the jig only contacts the jig by its mounting points, the lower can be mounted or removed quickly and without disassembling the jig .

Less Drilling: Advancements in The Router Jig's design allowed us to reduce the drilling portion of finishing the FCG pocket and trigger slot to only 2 holes! The integration of our bearing supported, fully optimized 5/16" end mill makes the milling portion faster, easier and safer than ever before. Removing the bulk of material by drilling is no longer necessary because the milling portion is so fast and easy. Our end mill design and bearing support system allow the user to remove material safely at a much faster rate than with other jigs. Other jigs rely upon the drilling portion to remove the bulk of material, which is extremely time consuming and labor-intensive. Beyond that, unsupported 1/4" end mills used with other jigs are not nearly as fast and effective in removing aluminum. In fact, with some 7075-T6 forged 80% lower receivers, milling with the inadequate cutting tools offered with other jigs can be downright frustrating and painfully tedious. As an added bonus beyond the time savings, our extensive testing revealed that optimal finish quality is achieved when fewer holes are drilled.

High-Visibility Milling: The 5D Tactical Universal 80% Lower Receiver Jigs utilize twin guide cavities, which are incorporated into the guide plate and therefore do not rely upon using the end mill shank for tracing an internal template. The result is a wide-open viewing area directly above the FCG pocket. With the Jig oriented in a manner where the buffer support is closest to the user, full visibility of milling is possible for all of the process. Additionally, the router support plate's viewing port is large enough to accommodate even a full-size wet/dry vacuum attachment for fast aluminum chip removal. Chips will immediately clear from the fire control group pocket as the user mills, and any other chips left behind can be easily removed with a vacuum. Keeping the fire control group pocket clear of aluminum chips during the milling operation is paramount in ensuring good finish quality. Other jigs force the user to partially disassemble the jig to remove the chips or offer no effective way for keeping the FCG pocket clean.

Super Fast Assembly: The Router Jig's professionally engineered design minimizes the number of total components and screws necessary for assembly. What's more, once the Jig has been assembled, it never needs to be disassembled! Only three screws and two quick-release pins are required for fixing or removing a lower from the Jig once it has been assembled the first time. Perfect for saving a ton of time during build parties or group purchases!

Integrated Depth Gauge: The Router Jig's 1-2-3 finishing process is made even easier by the integrated drill and end mill depth gauge that's numbered and built right into the top guide plate. This design allows the user to keep both hands free to adjust the router depth, and secure the drill stop collar quickly and with total precision. Not to mention, having the depth gauge integrated to the guide plate eliminates one tool that can be misplaced while finishing an 80% lower! Now where is my 10mm socket...?
