Forged Fire/Safe Marked 80% Lower Assembly: Your Build, Finished Right.
You’re looking at the kit that gets an AR-15 build off the bench and into your hands. This isn’t just a lower; it’s the complete foundation. We bundled a forged, FIRE/SAFE marked 80% lower receiver with a mil-spec lower parts kit, buffer tube assembly, and a butt stock because you need all of it to finish the job. No more chasing down separate parts. This kit is about getting it done.
What You Get in the Box:
- Forged 80% Lower Receiver (FIRE/SAFE Engraved): One solid starting point. Made from 7075-T6 aluminum, anodized in mil-spec black. The fire and safe markings are cleanly engraved, right where they should be.
- Complete Lower Parts Kit (LPK): All the springs, pins, trigger, hammer, and grip you need to make the lower functional. Standard mil-spec components that work.
- Buffer Tube Kit & Butt Stock: The buffer tube, spring, buffer, castle nut, and end plate are included. We add a standard collapsible stock so you have a complete receiver extension system ready to go.
Why This Forged Lower is the Right Choice
Forged 7075-T6 aluminum is the standard for a reason. It’s the same material used in military-spec M16 and AR-15 receivers. The forging process creates a dense, grain-aligned structure that’s exceptionally strong and resistant to impact. When you’re holding this lower, you’re holding the proven foundation for a reliable rifle. The magwell is broached cleanly for smooth magazine insertion and release. It’s a serious part for a serious build.
The FIRE/SAFE markings are engraved, not painted or laser-etched. This means they won’t wear off. They’re part of the metal. It’s a detail that matters for both function and a professional look once you’ve completed the machining.
Built Here, No Paperwork Required
This entire kit is 100% made in the USA. From the forging to the final assembly of the parts kit, it’s domestic manufacturing. And because it’s an 80% lower receiver, no FFL transfer is required. It ships directly to your door. You are the manufacturer upon completion. Know your local and state laws regarding 80% receivers before purchasing.
Who This Kit Is For
This is for the builder who understands that the lower receiver is the heart of the rifle. If you want the durability of a forged lower, the convenience of having all the lower components in one purchase, and the satisfaction of completing the final machining yourself, this is your kit. It’s perfect for a first build where you want quality parts from the start, or for an experienced builder adding another robust lower to the collection without the hassle.
What You Need to Know Before You Start
This is an 80% lower receiver. It is not a firearm. It requires machining to complete the fire control group pocket and other cavities using a jig, drill press, or router. The necessary tools are not included. You must have the knowledge, skill, and proper equipment to finish this receiver safely and correctly. Completing this receiver incorrectly can result in a non-functional or unsafe part.
Once you finish the machining, you will install the included lower parts kit and buffer assembly. The process of building is a major part of the value. You’ll know your rifle inside and out.
