Overview

This 80 percent lower receiver is manufactured by 80, a brand recognized for tight tolerances and consistent material quality. The forging is 100% inspected before leaving the facility, ensuring that the critical pocket dimensions, trigger slot, and fire control group geometry are within specification. The part is classified as a Category: Parts component and requires additional machining to become a functional receiver. Our fulfillment process prioritizes same-day dispatch on all in-stock 80% lowers, supporting builders who value turnaround time.

Features & Specs

• Material: 7075-T6 aluminum billet, hard-coat anodized per MIL-A-8625F, Type III, Class 2. This provides corrosion resistance and wear tolerance for extended service life.
• Dimensions: Mil-spec pocket depth and trigger slot width. All critical datums are within +/-0.005 inch of the original blueprint standard.
• Compatibility: Accepts standard AR-15 lower parts kits, buffer tubes, and pistol grip components. Designed for use with mil-spec upper receivers and bolt carrier groups.

Additional specifications include a threaded rear takedown pin detent hole, a reinforced trigger guard area, and a flared magazine well for faster reloads. The 80 percent lower is shipped without any fire control group components, buffer assembly, or stock. All machining surfaces are clearly marked with reference lines to assist in the finishing process.

Who It’s For

This 80% lower is intended for individuals who possess the necessary tooling, experience, and legal capacity to complete a firearm receiver. It is suitable for hobbyists, custom builders, and gunsmiths who require a blank canvas for personal projects. The part is not a functional firearm and is designed for those who understand the mechanical and legal requirements of finishing an 80 percent lower. If you are building a competition rifle, a precision platform, or a defensive carbine, this component provides the foundation. The very fast shipping offered on these 80% lowers ensures you spend less time waiting and more time in the workshop.

Shipping & FFL

All 80 percent lowers are shipped directly to your residential or business address. Because this product is classified as a non-firearm component (a partially machined receiver blank that requires substantial additional machining to become functional), it does not require transfer through a Federal Firearms License (FFL) dealer under current ATF regulations. However, it is your sole responsibility to verify that possession, purchase, and completion of an 80% lower is legal under your local, state, and federal laws. Some states and municipalities restrict or prohibit the purchase or possession of unfinished receivers. By placing an order, you confirm that you are legally eligible to own and complete this product. We ship via carrier with tracking and signature confirmation available upon request. Our team processes orders for same-day shipment on all in-stock items, delivering on the commitment to very fast shipping for every 80 percent lower purchased.
