Description
The Reticle Logo AR-15 Multi-Caliber Stripped Lower Forged Aluminum is the foundational component for building a custom AR-15. It’s a mil-spec forged lower receiver, stripped of all internal parts, that’s designed to accept multiple calibers like 5.56 NATO, .300 Blackout, and more, making it the perfect starting point for a personalized rifle build. I’ve built a few rifles on similar platforms, and the versatility of a multi-cal lower is a huge advantage—it lets you plan for future uppers without being locked into one cartridge.
Key Features
- Multi-Caliber Compatibility: Engineered to work with 5.56/.223, .300 AAC Blackout, 6.5 Grendel, and other popular AR-15 cartridges.
- Forged 7075-T6 Aluminum: Provides the classic strength and durability the AR-15 platform is known for, without unnecessary weight.
- Stripped & Ready for Customization: Arrives as a blank canvas, allowing you to select your own trigger, safety, bolt catch, and other internal components to your exact preference.
- Distinctive Reticle Logo: Features a clean, etched logo on the magazine well for a branded, professional look.
- Mil-Spec Design: Ensures broad compatibility with the vast ecosystem of AR-15 parts and accessories from brands like Aero Precision, Palmetto State Armory, and CMMG.

Here’s the thing—this isn’t a completed firearm, it’s a component. You’ll need to source a parts kit, buffer tube assembly, and an upper receiver to complete your rifle. The good news? It’s mil-spec compatible, which means finding those parts is straightforward. The process itself is rewarding, and at $71.81, this lower represents a solid value to kick off your project without breaking the bank. It ships to Missouri and compliant US states, so local builders can get started easily.
Who This Lower Is For
This stripped lower is ideal for the first-time builder looking for a straightforward, reliable foundation, or the seasoned enthusiast who wants a spare receiver for a new caliber-specific upper. If you enjoy the process of selecting each component and creating a rifle that’s uniquely yours, this is your starting block. It’s also a great option for someone planning a dedicated .300 Blackout build but who might want to swap to a 5.56 upper later on.
Pros & Cons
Pros: The multi-caliber designation offers fantastic long-term flexibility. The forged construction is proven and tough. The price point is very competitive for a branded, forged lower. The mil-spec design guarantees wide parts compatibility, so you’re never hunting for obscure components.
Cons: As a stripped lower, it requires additional investment in parts and tools to complete. You’ll need to go through an FFL for the transfer. The finish, while durable, is a standard black anodize—if you want Cerakote, that’s an aftermarket step.
Frequently Asked Questions
Q: What parts do I need to complete this lower receiver?
A: You’ll need a Lower Parts Kit (LPK), which includes the trigger, hammer, safety selector, pins, and springs. You also need a buffer tube kit (buffer tube, spring, buffer, and castle nut) and a stock. A pistol grip is typically included in an LPK but sometimes sold separately.
Q: Is this considered a firearm?
A: Yes. Even in its stripped state, the lower receiver is the legally controlled component of an AR-15. Purchasing it requires a background check and transfer through a licensed firearms dealer (FFL).
Q: Can I build a pistol with this lower?
A: Potentially, but it depends on how the receiver was originally classified by the manufacturer. You must start with a receiver that was transferred as “Other” or “Pistol” on the 4473 form to build a legal AR pistol. Always consult with your FFL during the transfer to ensure the proper classification for your intended build.
