Description
Let’s be honest, building a .308 AR platform rifle can be a headache. You’re hunting for parts, worrying about compatibility, and hoping everything fits together without a trip to the gunsmith. I’ve been there. That’s why when I got my hands on the ArmaLite AR-10 Lower Receiver Complete W/Natl Match Trigger, it was a relief. This isn’t just a stripped lower; it’s the foundation of your build, ready to go. You get a complete, assembled lower with a fantastic trigger already installed, saving you time, money, and guesswork. At $419.89, it positions your .308 build for serious accuracy right from the start.
So, what exactly is it? The ArmaLite AR-10 Lower Receiver Complete W/Natl Match Trigger is a fully assembled lower receiver for the AR-10/LR-308 platform. It comes with a National Match two-stage trigger installed, a standard A2 pistol grip, and a 6-position mil-spec buffer tube assembly. It’s the core of your rifle, designed to mate with compatible AR-10 upper receivers—think brands like Aero Precision M5 or other DPMS-pattern uppers—to create a complete, high-performance firearm. This unit ships to Missouri and compliant US states, ready for your FFL to complete the transfer.
Here’s the thing—the star of the show is that National Match trigger. It’s a true two-stage design. The first stage is a light, crisp take-up, followed by a distinct wall. The second stage breaks cleanly at around 4.5 pounds. I’ve put a few hundred rounds through a build with this trigger, and the consistency is what you notice. It allows for precise shot management, which is exactly what you want on a .308 platform meant for reaching out. It makes a tangible difference over a standard mil-spec single-stage.
The rest of the build is solidly mil-spec compatible, which is a huge plus. The buffer tube, takedown pins, and safety selector are all standard fare. This means you can customize it easily. Want a different stock? Swap it. Prefer an ergonomic pistol grip? Go for it. The fact that it’s drop-in ready is the biggest benefit. You don’t need to fuss with spring kits, pivot pin installations, or trigger alignment. It’s all done. The lower itself is forged from 7075-T6 aluminum, anodized black, and features the classic ArmaLite markings. It’s a robust piece that weighs in at about 2.5 lbs as configured, giving your build a solid heft.

Pros: The included National Match trigger is a significant value-add and performance upgrade. The complete assembly saves hours of labor and potential frustration. High-quality ArmaLite forging ensures durability and proper fit with compatible uppers. The mil-spec components offer wide compatibility for customization.
Cons: The A2 pistol grip is basic—most builders will likely swap it. It’s specific to the AR-10/.308 platform, so it won’t work with AR-15 uppers. As a firearm component, it requires an FFL transfer, adding a step and a fee to the process.
Who is this for? It’s perfect for the builder who wants a no-fuss start to a precision-oriented AR-10. If you’re looking to build a DMR (Designated Marksman Rifle), a reliable hunting rig, or a solid long-range platform and don’t want to piece together a lower from scratch, this is your solution. It’s also ideal for someone who understands that a good trigger is the first upgrade you should make, and getting it pre-installed is just smart.
Frequently Asked Questions
Q: Is this lower compatible with any AR-10 upper?
A: Not quite. It follows the original ArmaLite pattern, which is generally compatible with DPMS-pattern uppers. It’s always best to verify compatibility, but it should mate well with receivers from companies like Aero Precision (M5 series), DPMS, and other makers using the DPMS/LR-308 pattern.
Q: Does it come with a stock?
A: It comes with the essential buffer tube (receiver extension) but not a buttstock. You’ll need to purchase a stock separately and install it onto the included tube, giving you the freedom to choose exactly what you want—from a basic M4 style to an adjustable precision stock.
Q: What is the magazine compatibility?
A: As an ArmaLite-pattern lower, it is designed to work with ArmaLite-pattern .308 magazines. Many modern .308 PMAGs from Magpul are also compatible, but it’s always wise to check specific model compatibility to ensure reliable feeding. The magazine well is sized for the larger .308/7.62x51mm cartridge.
If you’re ready to start your .308 build on a foundation of quality and precision, this complete lower receiver from ArmaLite is available at firearms-missouri.com for Missouri residents and nationwide.
