MILLING
ADAPTER KIT
These
new AR15 lower receiver milling
adapters allow you to remove the
material from the fire control
area in AR type lower receivers. The adapters are sold
as sets. One adapter allows
you to drill the hole
locations and the other adapter
allows you to remove the material
using your drill press. With
these adapters you can remove the material from the fire control
pocket as well as the shelf inside
the fire control pocket. The
adapters have a hard anodized
coating that is gray in color
(shades of gray may vary).
This hard anodize finish give the
aluminum adapters very good wear
resistance.
The
milling adapters can be used to
finish AR15, AR10™
/ DPMS (0.308), and AR45 style
lower receivers.
They have also been used to
successfully complete Kevin's new
80% AR15 lower receivers.
Kevin has made it easier to
complete an 80% lower receiver by
leaving the fire control area
solid, drilling most of the side
holes and tapping the buffer tube
hole. Visit the tutorial
for more details on how to finish
Kevin's new 80%'ers. You can
get more details about Kevin's
80%'ers further down this page.
Also visit the tutorial
for
details on how to modify your
older style AR15 drilling jig so
the adapter kit will work with it.

-
(2) adapters
-
(4) bolts to secure the adapters
to the drilling jig
-

TRIGGER
SLOT MILLING ADAPTER KIT
If
you want a super easy and error
free way of cutting the trigger
slot in your lower receiver then
you need the trigger slot milling
adapter plate. This adapter
plate works just like the above
milling adapter kit for the fire
control pocket. You simply
drill through the guided holes,
flip the plate around and then use
the slot in the plate to guide the
included endmill to the exact
location. Visit the bottom
of this
tutorial for more information
on how to use this adapter plate.
This adapter plate kit isn't absolutely
necessary to finish a 80% lower
but it will make your life easier.
Included
with each adapter kit:
-
trigger slot milling adapter plate
-
special ground 1/4" solid
carbide endmill American
Made
-

AR15 LOWER RECEIVER
DRILL JIG
The original CNC machined setup blocks / drill guide for completing your 0% - 80% (casting or forged)
AR15 lower receiver.
The blocks have a black
anodized finish. I enjoy helping people get started in this hobby, so let me know if you ever have any questions. YOU WILL NOT FIND THIS KIND OF SUPPORT ANYWHERE ELSE!!!
A great deal of research and design time was put into these blocks to make sure they were as user friendly as possible. These blocks will help hold the receiver flat and square while you finish the work needed to get your receiver machined into a firearm. The
blocks are machined to mil-spec
standards, so every hole is right
on the money. The jig
includes the drilled and tapped
holes for the optional milling
adapter kits (listed
above).
Applications
Using
this jig is as easy as 1-2-3; (1) Place the blocks on both sides of the receiver and loosely tighten the two bolts, (2) Put the assembly upside down on the edge of a flat table and use another flat surface to make sure the back of the receiver is coincident with the back surface of the blocks ~this step is for locational
purposes~ (these two location surfaces must be to finish specs before use), (3) Then simply tighten the bolts and you are ready to drill the side holes or do any other work that needs to be done on your receiver.

Bolt Catch Hole and Buffer Tube Area
This
AR-15 jig will also aid you in drilling the bolt catch hole as well. Simply slide the block with the slots (as seen in the photo) over the receiver and clamp them together with a C-clamp and you are ready to drill the bolt catch hole, nice and straight without worrying about a crooked hole and ruined
lower. To get the pistol grip hole finished just slide the pistol grip onto the receiver and mark where the hole should be drilled. Then place a 2
½" block under the receiver (as shown) to easily drill the pistol grip hole. This way of drilling the hole is
by far the easiest method.
You can also use
this AR15 jig to make sure you get that tricky buffer tube area
drilled and tapped the first time. These blocks will even help you drill the front detent pin and any other work on top or bottom of the receiver.
The jig is so EASY to use, that you can finish out your receiver using little more than a cordless drill with the proper drill bits. No matter what side of the receiver you need to machine or drill, these setup blocks will insure you hold your receiver flat and square every time.
The blocks have a black
anodized finish, so you will be
able to use these blocks many
times. This is the same
mil-spec anodized finish that
the military uses, so you know
it will last a very long time.
The blocks are shipped with a
quick start instruction sheet to assist you in using your blocks for the first time. You
can also view the tutorial at
this link CNC
Gunsmithing Jig Tutorial.
This
AR15 jig will save you time and
money. No more trashing a
receiver because you drilled a
hole off position or at an
angle. This is a must have for
finishing an AR-15 receiver the
EASY WAY! Get yours today.

AR10™
/ DPMS (.308) LOWER RECEIVER SETUP
DRILL JIG
Due
to the increase interest of the
.308 AR rifle, I have developed an
AR10™ / DPMS (.308) drill
jig. No longer will you have
to modify your AR15 jig in order
to complete a .308 AR lower
receiver. The AR10™ jig is
based on the exact same concept as
my AR15 jig so you can reference
the AR15 tutorial at the top of
the page for details on how to use
the jig. Please also reference
the AR10™ blueprint for holes that
differ from the AR15 lower
receivers.
The
AR10™ jig will work perfectly with
my AR10™ lower receivers.
However, if you are wanting to
complete a DPMS style lower
receiver, then you need to note
the following. The front and
rear take down pins and the bolt
catch detent hole are not in the
exact same location on the DPMS
and the AR10™ style lowers.
In order to drill the hammer and
trigger holes, use the proper size
drill or gauge and insert them
into the selector hole and mag
catch hole of the jig and
receiver. With these two
reference points, you can then
drill the hammer and trigger
holes. See GEN2 mod
below for the newest AR10 drill
jig that more easily accepts DPMS
style lowers.
The
AR15 milling adapter kits will work
perfectly with this .308 jig. So
it is now just as easy to remove
the material from the AR10™ and
DPMS lowers as what it has been
with the AR15 lowers.
GEN2
mod (see below)
I've
updated the drill jig so it's now
easier to use DPMS style lowers
with the jig. The right side
of the jig now has 2 extra take
down holes and they are marked
DPMS ONLY (see pic below).
These 2 holes are only to be used
with DPMS style lower receivers.
To locate a DPMS style lower in
the jig, simply take a couple 308
style take down pins (not
included) and insert them from the
back side into the holes marked
DPMS ONLY. Then locate the
receiver on the pins and clamp the
other side of the jig. (see pic
below). Please note the Armalite
and DPMS take down pins do no line
up. If you are using an
Armalite style lower then you must
ignore the 2 holes marked DPMS
ONLY. The 308 take down pins
are larger diameter and longer
than standard AR15 take down
pins. If you don't currently
have the take down pins, then you
can substitute them with the
proper size drills or dowel pin.

Reference
the image below for the difference
between Armalite and DPMS style
308 lower receivers.
Armalite has 2 different 308
designs. The AR-10B which
accepts M14 style mags and the
AR-10A which accepts pmag style
mags.

Drills
 |
I have put together a list of the drills/tap you will
possibly need to purchase in order to complete your receiver. I don't sell these tools since you will be able to buy them cheaper from MSC www.mscindustrial.com
Below you will see the part number
of each tool. You may not
need every tool listed below
so be sure to check the tutorials
for the exact tools you will
need.
|
I
buy all the tooling for my shop from MSC. They have great quality and service. I would highly recommend using them instead of buying from somebody that is reselling the tools to complete the AR-15 receiver.
