    Click here if you already have a jig and would like to purchase only the tooling package.

    Now that you have made the wise decision to purchase the new Juggernaut Tactical AR-10 80% Lower Receiver, you will need to finish the machining procedure. We have made that part of your personal rifle build project very easy with this high quality jig kit. All you need is a drill press or a mill.

    • CNC-machined from solid aerospace T6 heat-treated 6061 billet aluminum
    • Laser-etched with Right/Left markings and drill hole sizes for convenience
    • Individually replaceable plates
    • Type III hard coat anodized
    • Optional high quality tooling package includes all bits required to finish your JT-10 lower. These are the same bits we use in our commercial CNC machines at the Juggernaut Tactical factory
    • If instructions are properly followed, the jig kit can be used to finish up to 25 lowers, or more
    • Made in the USA
    • Not guaranteed to fit all AR-10 lowers, due to differences in manufacturing

    Tooling package comes with:

    • 1 ea. 0.484" Cobalt Drill
    • 1 ea. 0.375" Cobalt Drill
    • 1 ea. 0.156" Cobalt Drill
    • 2 ea. 0.125" Cobalt Drill
    • 1 ea. 3/8" Carbide Endmill
    • 1 ea. 1/4" Carbide Endmill 

    For step-by-step video instructions on finishing your AR-10 80% Lower with our Jig Kit, go here

    Note: Our jigs are not compatible with billet lowers from 80% Arms or 5D Tactical, as they are not mil-spec on the outer dimensions.

    Note: Due to ATF final rule 2021R-05F (more info here), you cannot order an 80% Lower and jig-related products at the same time. If you have both in your cart, you will not be able to complete the checkout process.

    Very nice jig

    Nice finish and a well made jig. Only critique I would offer would be maybe provide the depth of each cut without having to watch a video. Maybe print it on the jig. Other than that, it looks to be a well designed jig. I finished the lower for my 6.5 Creedmoor over two evenings at about an hour each on a LittleMachineShop.com 4190 mini mill.

    Thumbs up

    5 stars for quality of jig. Gotta say 4 stars overall, just because of the lack of paper instructions. It’s pretty obvious how it functions but there was no drill depth information. I had to watch a video. More of a suggestion than a complaint, needs drill depths added to instructions.

    Juggernaut knows what they are doing like they are out using their own product and always improving it for us. Keep up the good work and I’ll keep ordering from you guys and refuting my friends to your products for their builds!
