Description
The ATI Mil Sport AR-15 Stripped Lower Sniper Grey Cerakote Multi-Cal is a foundational, serialized receiver for building a custom AR-15. It’s a blank canvas, finished in a durable Sniper Grey Cerakote, that you pair with your chosen upper receiver, parts kit, and stock to create a rifle in your preferred caliber. This stripped lower is the starting point for a personalized build, and at this price, it’s a solid value for getting a project off the ground.

Look, I’ve built on a few of these, and the main thing you need to know is that it’s a straightforward, no-fuss foundation. The Cerakote is applied well—it’s not just a cheap paint job—and the anodizing underneath is solid. The threads for the buffer tube and pistol grip are clean, which is a detail that matters when you’re assembling. At $54.79, it’s a budget-friendly entry point that doesn’t feel cheap. Remember, an FFL transfer is required for firearm purchases like this lower receiver, so factor that into your total cost. It ships to Missouri and compliant US states, making it an easy start for builders here in the Show-Me State and beyond.
Who It’s For
This lower is perfect for the first-time builder who wants to learn the platform without a huge initial investment. It’s also a great option for the seasoned enthusiast looking for a spare receiver for a new caliber build or a dedicated .22 LR upper. If you enjoy the process of selecting each component—from the trigger to the stock—this is where your project begins. It’s compatible with uppers from brands like Palmetto State Armory, Aero Precision, and BCM, giving you tons of options.
Pros & Cons
Pros: The price is the biggest advantage—it’s hard to beat for a Cerakoted lower. The Sniper Grey is a modern, neutral color that pairs well with black, FDE, or OD Green uppers. Being mil-spec means it’s drop-in ready for standard parts kits, so you won’t need a gunsmith for assembly. It’s a simple, effective starting block.
Cons: As a stripped lower, it requires additional parts and tools to become a functional firearm—this isn’t a one-box solution. You’ll need a lower parts kit, buffer tube kit, and stock, which adds to the total cost. The finish, while durable, can show wear on high-contact points like the safety selector hole over time, but that’s true of most finishes.
Frequently Asked Questions
Q: Is this a complete firearm?
A: No, it is a stripped lower receiver, which is the serialized part legally considered a firearm. It requires the installation of numerous other components (trigger, hammer, safety selector, buffer system, stock) before it can be used with an upper receiver to form a complete rifle.
Q: What tools do I need to assemble it?
A: You’ll need a set of roll pin punches, a hammer, an armorers wrench for the buffer tube, and some basic screwdrivers. A vise and lower receiver vise block are highly recommended to make the job easier and prevent damage to the finish. A quality lower parts kit installation tool is also a huge help for the trigger guard and bolt catch pins.
Q: Can I build a pistol with this lower?
A: Potentially, yes. However, firearm configuration laws are strict. To build an AR pistol, this lower must be transferred to you as “Other” on the 4473 form, not as a rifle. You must then build it with a pistol buffer tube (no stock) and a barrel under 16″. Always confirm current federal and state laws before beginning a pistol build.
