An "80 lower" is a term commonly used to refer to an 80% lower receiver, which is a partially completed firearm receiver that requires additional machining and assembly to make it functional. The term specifically refers to the lower receiver component of a firearm.
The designation "80%" indicates that the lower receiver is only partially finished, typically lacking the necessary holes and cavities for trigger group components, selector switch, and other fire control parts.
There are various types of 80% lowers available on the market, catering to different firearm platforms and models. Here are some of the common types of 80 percent lowers:
AR-15 80% Lower: The AR15 80 lower receiver is one of the most popular options. It is designed to be compatible with the AR-15 rifle platform, allowing users to build their own semi-automatic rifles chambered in .223/5.56mm.
AR-10 80% Lower: The AR10 80 lower receiver aka 308 80 lower is similar to the AR-15 variant but designed for the larger AR-10 platform, which is typically chambered in .308/7.62mm or similar calibers. Building an AR-10 requires specific parts and components to match the platform.
AR 9 80% Lower: The AR9 80 lower refers to an incomplete lower receiver specifically designed for building an AR-15 style pistol or rifle chambered in 9mm. It is designed to fit the AR-15 platform but with modifications to accommodate 9mm cartridges
Polymer 80 Lower: The Polymer80 lower is a type of 80% lower that is made from polymer material instead of metal. It is available in several different designs, including ones that fit the AR-15 and Glock platforms.
