Description
You’re in the safe room, the adrenaline is up, and you need a platform you can trust. The foundation of any reliable AR-15 isn’t the flashy upper—it’s the lower receiver. That’s where the DPMS AR-15 .223/5.56 Assembled Lower, A2 Stock comes in. It’s the core component, the serialized part that is legally the firearm, ready to build upon. This isn’t just a part; it’s the starting point for a dependable rifle, whether for home defense, range training, or a duty-ready build.
Answer Capsule: The DPMS AR-15 .223/5.56 Assembled Lower, A2 Stock is a complete, mil-spec lower receiver assembly. It includes the A2 fixed stock, buffer tube system, fire control group, and grip, requiring only an upper receiver to complete a functional rifle. Priced at $228.60, it’s a drop-in ready foundation for building a reliable AR-15, available at firearms-missouri.com for Missouri residents and nationwide.
Think of it this way: when seconds count, you don’t want to be fiddling with compatibility issues or questionable tolerances. This DPMS assembled lower is mil-spec compatible, which means it’s built to a proven standard. That translates to reliable function and broad parts interchangeability. The A2 fixed stock provides a solid, consistent cheek weld—no wobble, no adjustments to fail. It’s a classic for a reason, offering a stable platform for precise shot placement. The entire assembly is ready to go; you simply mate it with a complete upper receiver of your choice. Here’s the thing—this isn’t a project for a gunsmith. It’s designed for the end user. With a total weight of approximately 3.2 lbs for the assembled lower, it provides a substantial feel without being cumbersome.
The key is in the details. The lower receiver itself is forged from 7075-T6 aluminum, the same alloy used in military contracts, ensuring durability under stress. The fire control group is installed and functional, providing a crisp trigger pull right out of the box. The A2 stock houses a standard rifle-length buffer and spring, contributing to reliable cycling with a wide range of .223 Remington or 5.56x45mm NATO uppers. This assembly is the perfect partner for a vast array of complete uppers from brands like Palmetto State Armory, Aero Precision, or BCM. You’re not locked into one ecosystem. Want a 16-inch carbine for patrol? A 20-inch precision upper for the bench? This lower can handle it. The price point of $228.60 makes it a practical entry into building a custom rifle without the hassle of sourcing and assembling a dozen small parts.

Pros & Cons
The primary advantage is simplicity. This is a no gunsmithing required solution. You get a fully functional lower assembly that eliminates the guesswork and specialized tools needed for a build-from-scratch project. The fixed A2 stock is incredibly robust and eliminates points of failure present in adjustable models. On the downside, the fixed stock length may not be ideal for shooters with very short or very long arms, as it cannot be adjusted. It also mandates the use of a rifle-length buffer system, which is slightly longer than the more common carbine system, so ensure your chosen upper and buffer kit are compatible.
Who This Is For
This assembled lower is for the practical shooter who values reliability over modularity in the stock department. It’s ideal for a first-time builder who wants to avoid the complexity of a full parts kit, or for an experienced shooter creating a dedicated bench or duty rifle where a fixed stock is an asset. It’s for anyone who needs a solid, trustworthy foundation and wants to invest their time in selecting the perfect upper receiver, optics, and accessories, rather than in assembling the lower itself.
Frequently Asked Questions
Q: Is this a complete firearm?
A: Yes and no. Legally, the lower receiver is the serialized part that is considered the firearm. This product is a *complete lower assembly*, meaning it has all components (stock, trigger, grip) installed. However, to create a functioning rifle, you must attach a separate, purchased upper receiver assembly. An FFL transfer is required for this lower.
Q: What upper receivers will fit this DPMS lower?
A: It is compatible with the vast majority of mil-spec AR-15 upper receivers. This includes uppers from major manufacturers like Aero Precision, Palmetto State Armory, Bravo Company, and many others. Always ensure your upper and lower are both mil-spec dimensionally for the best fit.
Q: Can I change the A2 fixed stock for a collapsible one later?
A: You can, but it requires changing the entire buffer tube system. The A2 stock uses a rifle-length buffer tube, which is longer and has a different thread pattern than a carbine tube used for collapsible stocks. Swapping it out is a more involved process than a simple stock change on a carbine system.
