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 25 minutes! The AR-15/AR-9/AR-45 Router Jig PRO is by far the fastest and easiest AR-15 router jig on the market, bar none!
Universal Compatibility: The Router Jig PRO is truly universal
for all AR-15, AR-9, AND AR-45 80% Lower Receivers. A lower receiver is mounted and located in the 80% lower jig kit by features which are standardized and common to all AR-15 80% Lowers; the front takedown and buffer support. 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 AR-15, AR-9, OR AR-45 80% lower receiver regardless of exterior dimensions. Many other 80% lower 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 weapon machining 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, 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.
Universal Router Adapter incorporates two main features which eliminate any drawbacks to utilizing a router for milling
aluminum. First, the Adapter houses a massive high-speed bearing which assists in
centering the Adapter to the router, and supports the ReadyMILL in all
directions at all times, virtually eliminating 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.
The 5D Tactical ReadyMILL™
Our Patent Pending ReadyMILL is an absolute game changer in the realm of router based
80% lower receiver milling. We have always identified the end mill as a weak
link in many 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. Also, it's very common for the end mill to slip out of the router collet during use, creating a potentially dangerous situation for the user and/or ruining the lower!
To solve this, we took what's considered the best in CNC milling technology, and developed the world's first thermal fit tool holder for a router. The tool holder portion of the ReadyMILL threads directly to the router, and will never come loose. As a matter of fact, it only gets tighter during use. Next, we create a thermal fit between the tool holder and end mill, meaning the end mill cannot be pulled out of the tool holder. With this system, the required length of the end mill is only 1.5 inches and we can use a 5/16" diameter end mill because we are not limited by the collet size of the router! The ReadyMILL end mills is 2.25 inches shorter than any end mill in use with other 80% lower jigs. What this all means, is that our ReadyMILL is exponentially stronger, more rigid and safer than any other 80% lower end mill on the market. The ReadyMILL virtually eliminates tool chatter and contributes toward producing mirror-like finished results.
Centered and Parallel Features: Using the buffer support and front takedown to mount and locate the lower receiver in the AR-15 router 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.
1.5" Thick No-Touch Side Plates: Our No-Touch Side Plates, which were first pioneered by 5D Tactical, 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. 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 removing the side plates. The Jig can even be switched between platforms without removing the side plates!
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 1 hole! The integration of our bearing
supported ReadyMILL 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, the nearly 4" long end mills used with other 80% lower 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 80% lower 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 2 screws and one quick-release pin need to be removed to swap a lower once the jig 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 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 the laser marked hash marks increase visibility while adjusting depth settings. 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...?
