Advanced CNC Machines

CNCs are how to complete your 80% lower automatically. Finishing machines are easy to use, even for new gunmakers, engineered for efficient performance, and built of materials that will last. Set up your precision machine, load the program from an evergoing list of weapons platform plans available online, put in your 80% lower receiver blank, and the machine goes to work for you. The finished receiver is ready for final assembly with high-quality internal parts and is as compatible with other firearms components and accessories as any commercially produced lower receiver. The only differences are the lack of a serial number, no need for intrusive government background checks, and you get the satisfaction of making your firearm on your own. Create the gun you’ve always wanted, tailored to your shooting needs.
