An 80 lower empowers you to build your own carbine, pistol, or rifle from the comfort of your own home workshop. In addition to the fulfillment of forging one’s own firearm, you can also save money when compared to buying whole weapons outright.
At 5D Tactical, our AR-15, AR-308, and AR-9 80% lower receivers boast fast shipping directly to your home. Better still, all of our products are proudly made in the USA and to exacting standards of excellence.
Engineered for exceptional durability, and precision-machined with aerospace-grade aluminum for superior strength, our 80 percent lower receivers ensure that you’ll be starting your AR build off on the right foot.
Our 80 Percent Lower Kits and Parts Simplify Assembly
Easily convert our AR-15, AR-10, or AR-9 lowers into fully functional receivers with our 80% Lower Jigs. Shop our unfinished receivers and kits to get all the parts you need to complete your custom build with precision and efficiency.
80% lowers require the fire control group pocket to be milled out, which is completed with a handheld compact router. A hand drill or a drill press can be used to drill the safety selector, hammer, and trigger pin hole. We offer a variety of billet and forged AR-15 80 lower receivers of the highest quality as well.
