Choosing an AR15 Build Kit is the best way for you to get every AR-15 part you need to build your custom AR from the ground up. We create our AR15 Build Kit to include every spring, pin and screw you’re going to need to build your own AR-15 rifle at a fraction of the cost of buying a new one.
The options available range from 5.56 or 300 blackout build kits that include MagPul furniture, varying barrel surround styles, a lower parts kit and a Mil-Spec 80 lower.
Our AR15 Build Kits are made in the USA and packaged so that you can buy every piece you need for your build in a single purchase. AR-15 build kits can be shipped directly to your door without any FFL or paperwork because it’s not a functional rifle until you complete the 80% lower receiver.
Completion requires the builder to finish machining an 80% lower receiver using an 80 lower jig, removing the material from the fire control group area and drilling the trigger and fire/safety selector switch pin holes.
The completion of an 80 lower takes 1-2 hours, and installing the lower parts kit can take 1-2 hours. You can start your build in the morning and send brass down range by sunset.
Our AR15 Build Kits are 100% Mil-Spec and guaranteed to fit with any Mil-spec AR-15 parts manufacturer’s products.
