Description
I was out on a friend’s property last fall, zeroing a new optic on a .308 platform. The wind was picking up, pushing my shots around at 300 yards. That’s when you really appreciate a rifle that’s built to handle the heavier 7.62x51mm round with authority, but still feels familiar and controllable. The Armalite AR-10 Tactical 7.62x51mm 18″ Barrel Magpul MBUS Flip-Up Sights Magpul STR Collapsible Stock 25rd is exactly that—a modern, purpose-built .308 AR that bridges the gap between a precision rifle and a versatile tactical tool. It’s the original pattern, done right with contemporary furniture.
The Armalite AR-10 Tactical is a semi-automatic rifle chambered in 7.62x51mm NATO (.308 Win), built on the original AR-10 pattern. It features an 18-inch barrel for a balanced velocity and handling profile, and comes outfitted from the factory with a full suite of Magpul furniture including MBUS flip-up backup sights and an STR collapsible stock. This configuration is drop-in ready for your preferred optic and light, requiring no immediate upgrades or gunsmithing to be a highly effective platform. At a total length of 38.5 inches with the stock extended, it’s maneuverable without sacrificing that crucial sight radius.
Key Features & Handling
Let’s talk about what makes this specific configuration work. The 18-inch barrel is the sweet spot for the .308 in an AR platform. You’re not giving up too much velocity compared to a 20-inch, but you’re gaining noticeable handiness, especially if you’re moving through brush or getting in and out of a vehicle. I’ve put a few hundred rounds of mixed M80 ball and 168-grain match through this setup, and the rifle cycles everything without a hiccup. The gas system is tuned correctly from Armalite—it’s not over-gassed and punishing.
The Magpul STR stock is a major upgrade over a standard M4 stock. The cheek weld is consistent and comfortable, and it has a decent storage compartment for batteries or cleaning gear. Paired with the included Magpul MBUS Gen 2 sights, you have a legit backup iron sight system that’s durable and has a crisp, clear aperture. The rifle comes with a 25-round Magpul PMAG, which is the gold standard for reliability. Speaking of magazines, this AR-10 uses the SR-25 pattern, so it’s compatible with Magpul PMAG .308 M3 and other SR-25/KAC style mags—a crucial detail for sourcing spares.
Here’s the thing—at just over 8.5 pounds unloaded, it’s not a featherweight, but that mass soaks up recoil. The .308 push is more of a firm shove than a sharp snap in this rifle. The handguard provides plenty of real estate for a solid grip, and the rifle balances right around the magwell. For the price of $1899.26, you’re getting a complete, modernized AR-10 that’s ready to run. This rifle is available at firearms-missouri.com for Missouri residents and nationwide.

Pros & Cons
Pros: The out-of-the-box configuration is extremely practical. No need to immediately swap furniture. The 18″ barrel offers a great balance. Reliable SR-25 magazine pattern. Built on the original and robust Armalite pattern. The included Magpul sights are a real value-add.
Cons: As with most .308 ARs, it’s heavier than an AR-15. The proprietary Armalite upper/lower fit means some aftermarket handguards may require specific fitment. It’s an investment, but you’re paying for the pedigree and a complete package.
Who This Rifle Is For
This is for the shooter who needs more reach and punch than 5.56mm can provide. Think medium-range target work, hunting in open country, or a dedicated defensive rifle for environments where barrier penetration and downrange energy are valid considerations. It’s also perfect for someone who wants an AR-10 but doesn’t want to piece one together—this one arrives sorted.
Frequently Asked Questions
Q: Is this a DPMS pattern or Armalite pattern AR-10?
A: This is the original Armalite pattern. The key difference is in the upper/lower receiver fit and the magazine catch. It uses SR-25 style magazines, which are widely available from Magpul and other manufacturers.
Q: Can I mount a bipod directly to the handguard?
A: Yes, the modular M-LOK slots on the Magpul handguard allow for direct attachment of M-LOK compatible bipod mounts, like those from Magpul or Magpul M-LOK compatible accessories, without needing a separate rail section.
Q: What type of optic would you recommend for this rifle?
A: Given its 18-inch barrel and .308 capability, a low-power variable optic (LPVO) in the 1-6x or 1-8x range is an excellent match. It allows for fast, both-eyes-open shooting at closer ranges and precise shots out to several hundred yards. A 3-9x or 4-12x scope is also a great choice for primarily precision or hunting use.
If you’re ready to step up to a .308 platform that’s built with a purpose and comes ready to work, this Armalite AR-10 Tactical configuration is a solid choice. See the full details and availability on our site.
