Description
Let me paint you a picture. You’re looking for a .308 AR-platform rifle that doesn’t feel like you’re lugging a boat anchor through the woods, but still has the authority to reach out and touch something at distance. You want something reliable, straightforward, and built by folks who know their way around a forge. That’s the exact scenario where the Windham SRC 308 Carbine AR10 16″ Barrel, Flat Top, Key Mod Rail, 20 Rd Mag shines. I’ve put a few hundred rounds of mixed brass and steel-case through one, and it’s exactly the workhorse you’d expect from a name with Windham’s pedigree.
Here’s the direct answer capsule: The Windham SRC 308 is a semi-automatic carbine chambered in .308 Winchester/7.62x51mm NATO. It features a 16-inch barrel, a flat-top upper receiver for optics, a KeyMod free-float handguard for accessory mounting, and ships with a 20-round magazine. It’s a robust, no-fuss AR-10 pattern rifle built for durability and practical use, priced at $1422.49.
The heart of this rifle is its 16-inch chrome-lined barrel. It’s the sweet spot for a .308 carbine—maneuverable without sacrificing too much velocity. The gas system is mid-length, which I always prefer for a smoother recoil impulse and less wear on parts. The flat-top upper is a blank canvas. I’ve topped it with everything from a simple red dot to a 1-6x LPVO, and it’s rock solid. The real utility piece is the KeyMod rail. Look, M-LOK won the format war, but KeyMod is perfectly functional and there’s a ton of affordable accessories out there for it. Mounting a light and a handstop was a five-minute affair.
Where this rifle earns its keep is in its build quality. Windham Weaponry was founded by the original Bushmaster crew, and that institutional knowledge shows. The fit and finish are excellent. The controls are all mil-spec, which means you can upgrade the charging handle or safety selector with a vast array of aftermarket AR-10 parts. The rifle cycled everything I fed it—from cheap Tula to premium hunting loads—without a hiccup. It’s a tool, not a jewel, and it’s built to be used. At just over 8 pounds unloaded, it’s manageable for extended carries, a data point that matters more than you think after a long day afield.

Pros & Cons: The pros are clear: proven reliability, a great barrel, and a straightforward design that’s mil-spec compatible and truly drop-in ready for optics and accessories. The cons? KeyMod is a bit dated, and the trigger is a serviceable but heavy mil-spec unit—an upgrade most shooters will consider. That said, you’re getting a complete, tested rifle from a legendary manufacturer without any proprietary quirks that lock you into one ecosystem.
Who is this for? This is for the Missouri hunter who wants a versatile woods rifle for hog or deer, the shooter who wants a capable defensive carbine in a potent caliber, or anyone building a practical, general-purpose .308 platform. It’s not a 1000-yard benchrest gun; it’s a 0-500 yard hammer. It’s also an excellent foundation for a project gun. Want to swap the handguard to M-LOK later? Go for it. The rifle is available at firearms-missouri.com for Missouri residents and nationwide.
Frequently Asked Questions
Q: Does this use SR-25 pattern or Armalite AR-10 pattern magazines?
A: It uses the more common and widely available DPMS/SR-25 pattern magazines. The included 20-round Magpul PMAG LR/SR is a great start, and many other brands like Lancer and Hexmag make compatible mags.
Q: Is the barrel threaded for a muzzle device?
A: Yes, the 16-inch barrel comes with a standard 5/8×24 thread pitch, which is the common threading for .308 caliber muzzle brakes, compensators, or suppressors. A standard A2 birdcage flash hider is installed from the factory.
Q: Can I use my existing AR-15 accessories on this rifle?
A: Some, but not all. Furniture like pistol grips and stocks that fit a mil-spec buffer tube will work. However, the lower parts kit, bolt carrier group, and charging handle are specific to the larger AR-10 platform. Always verify part compatibility for the DPMS pattern before purchasing.
