The Sons of Liberty Gun Works complete lower receiver is a fully assembled AR-15 lower chambered for 223 Remington/556NATO, ready to mate with an upper of your choice. It ships with the fire control group, buffer assembly, stock, and grip already installed, so the buyer who wants a finished foundation without sourcing small parts can get straight to the build. Shooters putting together a duty-grade carbine or a competition gun will recognize the value in a forged receiver that has already been assembled to spec. Pair it with a stripped or complete upper to finish the rifle.
The receiver starts as a mil-spec 7075-T6 forging from the lead forge in the U.S., then gets fully machined to remove flash marks left by the forging process. The maker holds tighter tolerances than typical forged lowers, which translates to a better upper-to-lower fit. The finish is matte black hard-coat anodized to Mil 8625 Type 3 Class 2. Inside, you get a Liberty Fighting Trigger, a mil-spec H buffer, a mil-spec A2 stock, and a mil-spec A2 grip, along with an enhanced aluminum trigger guard. The unit weighs 32 ounces and measures roughly 3 inches across the receiver body. If you want a bare receiver to build from scratch instead, the stripped version covers that route.
This lower suits the shooter assembling a 5.56 carbine for home defense, range work, or competition who wants the lower half handled and tested before it ships. Drop a complete upper on top and headspace is set, function-check, and you have a working rifle. Buyers comparing build paths often look at the matched receiver sets or a complete 5.56 carbine alongside this option. Browse the rest of our AR build components and rifles to round out the project.
It is chambered and assembled for 223 Remington/556NATO. Because the lower itself does not contain the chamber, it pairs with standard AR-15 uppers in 5.56 and other AR-15-pattern calibers, but the included furniture and buffer are matched to a standard carbine setup.
Yes. It ships complete with a Liberty Fighting Trigger, a mil-spec H buffer, a mil-spec A2 stock, a mil-spec A2 grip, and an enhanced aluminum trigger guard. You only need to add a complete upper to finish the rifle.
The receiver is machined from a mil-spec 7075-T6 forging sourced from the lead forge in the U.S. It carries a matte black hard-coat anodized finish meeting Mil 8625 Type 3 Class 2 standards.
Yes. A complete or stripped lower receiver is the serialized firearm part under federal law, so it must ship to a licensed FFL dealer for transfer. We handle the paperwork on our end once your dealer's information is on file.
A stripped lower is just the bare serialized receiver with no internals. This complete version comes assembled with the fire control group, buffer, stock, and grip already installed, saving you the parts sourcing and assembly time.
