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 .308/AR-10 5D Tactical Jig Pro is by far the fastest and easiest router based AR-15 jig on the market, bar none!
Universal Compatibility: The Router
Jig PRO is truly universal for all .308 and AR-10 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 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 .308 or AR-10 80% lower receiver regardless of exterior dimensions. Many other 80% lower receiver 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,
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 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 80% lower receiver 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 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
Centered and Parallel Features: Using the buffer support and
front 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 .308 and AR-10 style lower receivers 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
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 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 that 10mm socket...?
