So What Is An 80 Percent Lower Jig?

An 80 percent lower jig is a variation of a receiver blank you use as a primary component for building an AR-15. Receiver blanks are a kind of gun frame that houses some of the firearm’s action pieces. Blanks are the uncompleted parts that do not come with a serial number. What it means is that you have to do the finalization of the item if you want it to work. That is where an 80 percent lower jig comes in handy. The jig is like a template or stencil you will use to finish the receiver. While some companies and manufacturers produce the equipment in factories and workstations. You as a Do-It-Yourself gunsmith will make your receiver from scratch using the 80 percent lower jig. You will have to do some minute cutting and drilling to get that ideal receiver. The primary objective of the lower jig is to transform your receiver blank into a stripped receiver. Once you finish all of that, the result is the same with a pre-calibrated and FFL-registered stripped receiver.
