The Polymer 80 Compact Pistol Frame PF940C kit is designed to replace the frame of a compact size Glock pistol such as the Glock 19 or 23. It can be built for either 9mm luger or 40 S&W caliber with only a few parts difference. The kit is easy to complete with the jig and bits included. The only required tools are a drill and files.

What is an 80% Lower Receiver?
This 80% lower receiver is manufactured in the USA in our precision machine shop in Greer, South Carolina. Sometimes referred to as a “paperweight”, the 80% lower is not considered a firearm or a complete receiver until you finish it. Therefore, no FFL is required in order to buy or ship the product.
When you are looking to build out your AR, buy the American-made 80% forged lower from Palmetto State. Nothing leaves our machine shop that doesn’t meet our precision standards for quality. You can be assured of a highly accurate and aligned lower. Made with forged 7075 aluminum, your 80% lower is built with the strongest aluminum and provides a slight advantage in weight compared to a billet option.
Some manufacturers use cheaper aluminum and are not as concerned with precision machining, leaving you dissatisfied with an inferior product. At Palmetto State Defense, we stand behind the quality of our 80% lowers.
With an 80% forged lower, there is no serial or registration required since it is not a firearm. If you live in a not-so-friendly gun state, be sure you are well aware of the laws before purchasing.

Why a Polymer AR-15 80% Lower?
Polymer 80% lowers have been well-tested and proven among the AR-15 and 80% lower community. This ultralight lower affords the same ruggedness as any aluminum lower, yet its construction also affords many unique benefits.
If you’re nervous about machining an 80% lower, this polymer lower will be the perfect way to ease into the practice. Polymer is incredibly simple to drill and mill, and the material is forgiving.
The G150 Phoenix Includes Its Jig – and it’s the most affordable!
