80% Arms AR-15 Easy Jig, Manual

Page: 12 / 20

STEP 12:
Prepare the jig to mill the rear shelf.
TIP: If your lower already came with the rear shelf / lug area milled out,
skip step 12 and 13 and move directly to step 14.
Remove the Router Base Support Plate #7 and the Trigger Pocket Template
#5. Set the Rear Shelf Template #6 on top of the Template Spacer #4 so
that the longer hole is closer to the buffer tube hole, and the raised lip of the
template is facing up. Next, place the Router Base Support Plate #7 over
the lip of the template with the recessed bolt holes facing up. Attach the
plate using the Template Bolts #9. Tighten the bolts to the jig walls in an
alternating pattern. Secure the assembled jig in the vise with the buffer tube
hole facing away from you.
Next, pull out the top rear Jig Bolt #08 so you do not mill through it.
Removing the jig bolt completely can cause the lower to slip downward if the
vise is not tight enough. Re-insert and thread the tip of the bolt 7/8” through
the top left jig wall threaded hole. The tip will go into the edge of the lower
and keep the lower from slipping without getting in the way of the end mill.
