ArmaLite A10SBF2 AR-10 Super SASS II 7.62x51mm 20in 20+1
Pros & cons
What works
- Weighs 11.2 lbs — the mass directly aids in recoil reduction and bench stability.
- 20-inch barrel with 1:11.25 twist — optimal for stabilizing 168-175 grain match .308 loads.
- Six-position adjustable gas block — enables reliable tuning for suppressor use or light loads in under 60 seconds.
- Includes Magpul MBUS Gen2 backup sights — a $120 value pre-installed and zeroed from the factory.
Trade-offs
- No optic, mount, or bipod included — requires an immediate additional investment of $500+ for a functional precision rig.
- The ArmaLite Tactical Brake is aggressively loud and concussive — bystanders will feel the blast within a 10-foot radius.
- The 15-inch handguard lacks a QD sling point at the front — requires an M-LOK adapter for a two-point sling setup.

About this product
The ArmaLite A10SBF2 AR-10 Super SASS II is a semi-automatic, precision-configured AR-10 platform rifle chambered in 7.62x51mm NATO, purpose-built for consistent long-range accuracy and suppressor-friendly operation. This represents an evolution of the original Super SASS program, executed by the original AR-10 patent holder, with modern modularity features like a full-length M-LOK handguard and a fully adjustable gas block. As a lead armorer dealing with Title II hardware, I consider rifles like this from ArmaLite to be in a class of their own for out-of-the-box precision platform builds that don't require immediate gunsmithing.
What is the ArmaLite A10SBF2 AR-10 Super SASS II used for?
This rifle is designed for precision-oriented long-range shooting applications, both competitive and practical. Its 20-inch barrel, rifle-length gas system, and adjustable two-stage trigger are engineered to support consistent shot placement at extended distances, making it suitable for PRS-style matches or extended-range field courses. The adjustable gas block, which provides six discrete settings, allows the shooter to tune cycling for specific ammunition loads and suppressor use, effectively making it a platform for long-range suppressed work without modification.
How does the A10SBF2 AR-10 compare to the Stevens 334 .308 Win?
The ArmaLite is decisively better for sustained, rapid follow-up shots and modular accessory mounting, while the Stevens 334 Rifle is a more cost-effective choice for pure bolt-action precision. Where the A10SBF2 uses a semi-automatic action with a fully adjustable gas system and M-LOK handguard for mounting bipods, lights, and lasers, the Stevens 334 is a traditional bolt-action with a synthetic stock, offering simpler operation at roughly one-third the cost but without the rapid-fire capability or modular rail space.
What does it weigh and what are the dimensions?
This rifle has an unloaded weight of 11.2 pounds and an overall length of 39.5 inches with the Magpul PRS Gen2 stock fully collapsed. The barrel is precisely 20 inches long with a 1:11.25 twist rate, and the handguard is a 15-inch aluminum M-LOK unit providing 180 degrees of accessory mounting real estate. For reference, when fitted with a 20-round PMAG and a typical 24-ounce bipod, the ready-to-shoot weight exceeds 13 pounds, which is substantial but contributes directly to recoil management and stability on the bench.
Who is this NOT for?
This rifle is not for budget-conscious hunters or first-time AR platform buyers seeking a general-purpose carbine. At just over $3,300 and weighing over 11 pounds unloaded, it represents a significant financial and physical investment focused squarely on precision performance, not casual plinking or brush hunting. If your primary use is short-range target shooting under 300 yards or you're looking for a lightweight Stevens 555 Sporting O/U, this rifle's specialized features and heft will be underutilized and potentially cumbersome.
What's in the box?
The rifle ships with Magpul MBUS Gen2 front and rear flip-up backup iron sights installed, one 20-round Magpul PMAG .308 AC magazine, and the factory-installed ArmaLite Tactical Muzzle Brake. ArmaLite includes a minimal kit containing a chamber flag, operator's manual, and a single Allen key for stock adjustments, but notably does not include a case, optic, bipod, or sling—common accessories that represent an additional $500-$1,500 investment for a functional precision setup.
Is the ArmaLite A10SBF2 worth it at $3319.99?
Yes, if you require a suppressor-ready, out-of-the-box precision AR-10 that doesn't need immediate aftermarket trigger, gas block, or stock upgrades to perform. The combined cost of a base AR-10, a quality two-stage trigger ($200), an adjustable gas block ($120), a precision stock like the PRS Gen2 ($250), and backup sights ($100) quickly approaches this rifle's price before assembly and headspacing. For the shooter who values a factory-built, headspaced, and tested system with proven durability from the original AR-10 manufacturer, this price reflects a complete, no-gunsmithing-required precision platform.

Frequently asked questions
- Is it compatible with standard AR-10 magazines?
- Yes, the A10SBF2 uses the SR-25 pattern magazine, which is the industry standard for modern AR-10 platforms. It ships with a 20-round Magpul PMAG .308 AC, but will accept any SR-25 compatible magazine from brands like Magpul, Lancer, and KAC without modification.
- Does it fit in a standard 42-inch rifle case?
- No, with an overall length of 39.5 inches, this rifle will not fit in most standard 42-inch cases when the muzzle brake is installed, as the brake adds approximately 2.5 inches. You will need a hard case with an internal length of at least 44 inches, such as a Pelican 1750, for safe transport with the brake attached.
- How long does shipping take for an online-only firearm?
- Processing and shipping for online-only firearms typically takes 3-5 business days after FFL verification, not including transit time. All firearms must ship to a licensed dealer (FFL) for pickup, and you must provide your chosen FFL's information before the order is processed—allow a full 7-10 business days from order to dealer arrival.
- Can I return it if I don't like the trigger pull?
- No, Ironclad Armory does not accept returns on firearms due to subjective performance preferences like trigger feel, once the transfer has been completed at your FFL. All firearms are test-fired and inspected prior to shipment, and returns are only accepted for legitimate mechanical defects, which must be reported within 72 hours of FFL pickup.
- Does this work with a .308 silencer like a Surefire SOCOM762?
- Yes, the adjustable gas block has specific settings for suppressed fire, and the 5/8x24 threaded muzzle is standard for .308 suppressors. When using a can, you will need to adjust the gas block to its suppressed setting (typically position 4 or 5 out of 6) to manage blowback and ensure reliable cycling with the increased backpressure.
