80% Arms sells AR-15 and .308 80% Lower Receivers, 80% Lower Jigs and other accessories which allow you to legally build a firearm at home in most states.
INCREDIBLY PRECISE
We utilize state of the art 5-axis CNC machines to mill all our .308 and AR-15 80 percent lower receivers to incredibly precise tolerances using premium billet aluminum.
RIDICULOUSLY EASY
We also offer our patented AR-15 and .308 Easy Jigs® which is the first 80% lower jig that makes it ridiculously easy for a non-machinist to finish their 80% lower in under 1 hour with no drill press required.
100% SATISFACTION GUARANTEED
Products manufactured by 80% Arms carry a lifetime warranty against manufacturing defects. We will promptly replace or repair any product that we determine to be defective.
Need some tools or spare parts to finish that lower? Our products and tools are specifically designed for precision cutting, and longevity while cutting the remaining 20% out of an 80% lower receiver using our Easy Jigs®. All of our tools and products are manufactured with precision in the USA!
What is included in an 80 lower jig toolkit?
Each kit includes the following:
Speedmill™ (Coated Solid Carbide End Mill option available)
3/8 Drill Bit
5/32 Drill Bit
21/64 Drill Bit
Our speed mills are now adjoined with our new heat-shrunk tool holder, this combination virtually eliminates deflection and total runout to ensure a CNC like quality finish.
Replacement 80% lower jig parts
There are many benefits to purchasing spare or replacement parts for your jig. Purchasing replacement parts not only extends the life of your 80 percent lower jig but also removes need to purchase a new 80% lower jig should you ever break or lose a part. Just like any tool, it's important that you keep up with maintenance, and replace worn parts and components! That being said, our Easy Jig® Gen 3 is designed to last a lifetime, and as long as you take care of it; It will always take care of you.
