The Polymer80 AR and pistol jigs are back.

Polymer80 helped make finishing your 80% lower and 80% frame easier than ever, thanks to its universal 80% jig made for AR-15 receiver blanks. This polymer jig includes the needed bits and end mills to finish any mil-spec receiver. P80's jigs were originally made to work with their propriety polymer lowers, but their AR-15 jig also provides guidance for completing aluminum (billet or forged) lowers.

Why a Polymer Jig and Lower?

Fabricating polymer is easier than machining aluminum. The material is easier to cut and drill, and the raw receiver blanks are typically more affordable than their billet or forged counterparts. Although P80 jigs are considered disposable, they can be reused to complete multiple blanks if care is taken to preserve the drilling and milling guides.

Polymer80 AR-15 Jig: What's Included

  • (1) 2-sided jig
  • (3) trigger guides
  • 9mm HSS end mill
  • 5/16ths drill bit
  • 3/8ths drill bit
  • 5/32nd drill bit

To complete your polymer AR-type lower with the RJ556U Jig, we recommend using a drill press with an appropriate work-holding vise. Calipers should be used to confirm milling depths, and basic round and flat files should be used to clean up rough edges after initial fabrication.

Polymer80 Frame Jigs

They're back! Polymer80's GLOCK-compatible 80% frame jigs are designed to work with all currently available P80 frames. These jigs are designed to assist in drilling the frame's pin holes and finishing the top of the frame to make it ready for your GLOCK parts kit and slide installation.

P80 Frame Jigs are available for the following Polymer80 GLOCK frames:

Polymer80 Frame Jig: What's Included

  • 2-sided jig
  • 3mm drill bit
  • 4mm drill bit

We recommend you also have a tabletop vise to hold the jig and frame. A Dremel and #9904 bit works best for completing the P80 frame's slide section. Round files are best for light sanding and finishing before assembly.

"What parts do I need to finish my frame?"

A GLOCK Build Kit includes all parts required to assemble your 80% GLOCK frame after you've fabricated it with your P80 jig. That includes the frame internals, barrel, and slide assembly. Front and rear sights and magazines sold separately.

State Laws May Vary

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
