Description
You’ve been eyeing a precision .308 platform, but the price tags on some custom builds or boutique brands make you wince. You want a rifle that’s ready for serious work—target shooting, hunting, or duty—without needing a second mortgage or a master gunsmith. The challenge is finding that sweet spot where proven performance meets practical value. That’s where the factory-built, purpose-driven option comes in.
The Armalite AR-10A Super SASS .308 Win/7.62, 20″ Barrel, Black Magpul PRS Stock Black, 20 rd is a semi-automatic precision rifle built on Armalite’s original AR-10 pattern. It’s a complete, out-of-the-box system designed for long-range accuracy, featuring a free-floated stainless steel barrel, an adjustable Magpul PRS stock, and a two-stage trigger, all for a price point of $2929.50 that undercuts many comparable custom configurations.
Built for Accuracy, Priced for Reality
Let’s be clear: this isn’t a plinker. The Super SASS (Semi-Automatic Sniper System) is built with a specific mission. The heart is its 20-inch, button-rifled, stainless steel barrel that’s free-floated within the aluminum quad-rail handguard. This setup minimizes external pressure on the barrel, promoting consistent shot placement. The included two-stage trigger provides a clean, predictable break that’s a massive upgrade over a standard mil-spec unit—no gunsmithing required to get a decent pull right from the start.
The Magpul PRS (Precision Rifle/Sniper) stock is a major value-add here. On its own, it’s a $250+ component. It offers length-of-pull and cheek riser adjustments, letting you lock in a perfect weld behind the optic. This rifle weighs in at approximately 12.5 pounds unloaded, which is substantial. That heft, combined with the rifle’s overall length of around 40 inches, soaks up recoil and aids stability from a supported position, but it’s not a rifle you’ll want to carry all day on a stalk.

The Practical Trade-Offs: Pros & Cons
Pros: The biggest advantage is its completeness. You get a precision-oriented barrel, a superb stock, and a good trigger in one package. It uses the original Armalite AR-10 pattern, meaning parts like bolts, carriers, and magazines are compatible with other rifles in that lineage, not the DPMS pattern. This avoids a lot of consumer confusion. It’s a robust, reliable platform that’s drop-in ready for your optic and bipod.
Cons: That readiness comes with weight and bulk. At over 12 lbs, it’s a bench or prone rifle first. The quad-rail handguard is functional but adds weight compared to modern M-LOK options; you can add rail sections only where needed. And while the price is competitive for what’s included, it’s still a significant investment—you’re paying for specialized capability you may not need if you just want a basic .308 rifle.
Who This Rifle Is For
This rifle is for the shooter who understands the value of a unified system. It’s for the precision rifle competitor on a budget who doesn’t want to piece together a build. It’s for the hunter setting up over a long field or powerline cut. It’s for the serious marksman who wants a durable, semi-auto .308 that can reliably hit man-sized targets at 800+ yards without the fuss of a custom gunsmith bill. If your goal is sub-MOA accuracy with factory match ammo from a proven, no-nonsense platform, this is a compelling option. It is available at firearms-missouri.com for Missouri residents and nationwide.
Frequently Asked Questions
Q: Is this a true AR-10 or a DPMS-pattern rifle?
A: This is built on Armalite’s original AR-10A pattern. This matters for parts compatibility—specifically the bolt carrier group, barrel extension, and magazines. It uses Armalite-pattern mags, which are distinct from DPMS/SR-25 pattern magazines.
Q: What kind of accuracy can I expect?
A: With quality .308 Winchester match ammunition, sub-MOA (Minute of Angle) groups are a reasonable expectation from the free-floated, stainless steel barrel and match trigger. Your results will depend heavily on ammunition selection and shooter skill.
Q: Can I easily change the handguard?
A: Yes, but you must ensure any replacement handguard is designed for the original Armalite AR-10A platform, as the barrel nut and upper receiver dimensions differ from the more common DPMS pattern. This is a key compatibility point to check.
