What is an 80 Percent Lower Receiver? ⌛
It is an unfinished lower receiver that contains only 80% of the milling and drilling did, allowing it to be legally sold as a non-firearm. It can be completed with some basic tools and knowledge of firearms assembly, and are popular among home gunsmiths looking to build their own AR-15 or other modern sporting rifles.
📌It provides an excellent base for the gunsmith, allowing them to customize the firearm to their exact specifications without having to purchase a complete, factory-assembled rifle.
📌 These receivers are machined from high-quality materials and feature pre-machined holes for attaching the hammer, trigger, safety selector, and other components.
📌 They can be finished using very simple tools in just a few minutes.
📌 They offer increased accuracy and dependability.
📌 Other features include increased safety due to the lack of serial numbers or markings that could identify the firearm’s owner or source of origin.
🎯 Billet Lower Receivers are machined from a solid block of aluminum alloy and can be shaped into almost any design or style desired.
- This type offers superior strength and durability due to the quality of material used in its construction, as well as being highly customizable with unique designs and styling options available.
🎯 Forged Lower Receivers are created by hammering two pieces of material together, usually aluminum or steel, to form a strong yet simple frame.
- These are relatively easy to work with and provide excellent structural integrity, making them ideal for budget builds or those on a tight timeline.
- The downside of these receivers is that they lack the customizability and high-end aesthetic options available in billet models.
🎯 Polymer 80% Lower Receivers are made from durable reinforced polymer materials designed to withstand even the harshest conditions while providing users with cost-effective alternatives to metal lowers.
- These offer greater flexibility in how they appear as opposed to traditional metal lowers, while still offering strength and durability at an affordable price point.
- Some polymer receivers may be prone to cracking if not properly handled during installation or use.

How to Finish an 80% Lower? 🔰
🛠 Necessary tools:
- ✔️ a drill press with various bits and drills;
- ✔️ a milling machine with end mill bits;
- ✔️ drill stops;
- ✔️ other specialized tools to ensure precise measurements during the process.
✅ Start by drilling out the trigger pin hole using a 1/4″ drill bit set on the lowest speed setting on your drill press for best accuracy results.
✅ Next, use your end mill bit to remove metal from around the edges of the trigger guard pocket so that it fits flush against the receiver when installed.
✅ Make sure that all of your cutting edges are straight and even
✅ The next step is to machine out both sides of the magazine well in order to create space for inserting your magazine when fired. Use either an end mill bit or router bit depending on what type of material your 80% lower is made from – aluminum or polymer – and once again remember to keep all cuts clean and even in order to ensure proper function after assembly.
✅ Finally, install any safety features such as fire control components required by law in order for your AR-15 rifle or pistol build to be legal according to Federal regulations.
⭕ Be sure to check with local laws before beginning this step as they may differ from state to state regarding acceptable firearms configurations allowed within each jurisdiction.
