Build on a Foundation That Matters

You’re building an AR-15. You want it to run, and you want it to last. It starts right here, with the lower receiver. This isn’t just another piece of aluminum; it’s the core of your rifle. We put together this complete assembly because you need parts that work together, sourced from people who know what they’re doing. This bundle gets you from an 80% lower to a finished lower assembly with one purchase. No hunting for separate parts. No guessing on compatibility.

What You’re Getting

This is a complete kit. You supply the tools and the finishing work; we supply the high-quality foundation.

• One (1) Forged 7075-T6 Aluminum 80% Lower Receiver: This is the real deal. Forged, not billet. 7075-T6 is the same alloy used in military-spec lowers. It’s harder and stronger than the 6061 aluminum you often see. It’s built to handle stress and last for thousands of rounds. The magwell is professionally broached for smooth, reliable magazine changes.
• Fire/Safe Selector Markings: Cleanly engraved, not painted or laser-etched that can wear off. These are deep, legible markings that give your build a professional, finished look right from the start.
• Complete Lower Parts Kit (LPK): All the springs, detents, pins, and fire control group components you need to complete the lower. We use kits with a solid reputation for proper fit and function.
• Buttstock & Buffer Tube Assembly: A full stock and mil-spec buffer tube system. This isn’t a placeholder; it’s a functional stock to complete your build. The buffer tube is properly threaded and includes the castle nut and end plate.
• Anodized Mil-Spec Black Finish: A durable, hard-coat anodized finish that matches standard upper receivers. It resists wear and corrosion.

The Details That Make the Difference

Anyone can sell you an 80% lower. Here’s why this one is different.

Forged Strength: Forging aligns the metal grain structure, creating a part that is inherently stronger and more impact-resistant than one milled from a solid block of billet aluminum. For a critical stress-bearing component like your lower receiver, this isn’t just a spec sheet bullet point—it’s peace of mind.

100% Made in the USA: This isn’t imported. It’s manufactured, finished, and assembled from American materials. You’re supporting domestic machining and manufacturing, and you’re getting a product held to a known standard of quality.

No FFL Required: This is an 80% lower receiver, legally not a firearm. It ships directly to your door. The responsibility and the satisfaction of completing the final machining steps are yours. Know your local and state laws.

The Complete Package: We saved you the legwork. Instead of buying a lower, then a parts kit, then a stock and buffer system separately—and paying shipping on each—we bundled it. You save time, you save on shipping, and you know all the components are designed to work together. This bundle is built for the builder who wants to get started without the hassle.

Is This Kit For You?

This kit is perfect if you’re doing your first 80% build and want a straightforward, reliable path. You get all the major components in one shot. It’s also ideal for the experienced builder who appreciates the value and strength of a forged lower and doesn’t want to piece together another lower assembly from scratch.

If you value American manufacturing, material strength, and a no-nonsense approach to building, this is your lower. It’s for the builder who would rather spend time at the range than shopping for small parts online.
