Threaded 1/2x28 to fit standard AR barrels, this A2 flash hider helps reduce visible muzzle flash, protects your barrel crown, and offers a rugged, duty-ready finish at a price that makes sense for both builders and upgraders.
Mil-Spec A2 Flash Hider for AR-15 / 5.56 NATO
This Anderson flash hider follows the proven A2 “birdcage” design used on countless service and duty rifles:
Caliber: 5.56 NATO / .223 Remington
Thread Pattern: 1/2x28 – standard AR-15 muzzle threads
Type: A2-style flash hider / flash suppressor
Platform: AR-15 and other 5.56/.223 rifles with 1/2x28 threaded muzzles
The A2 configuration is widely trusted because it’s simple, effective, and robust. It’s a perfect match if you’re building a clone-style AR, finishing out a stripped barrel, or replacing a worn or damaged muzzle device.
Effective Flash Reduction & Crown Protection
While compact and affordable, this Anderson A2 flash hider still performs essential functions at the muzzle:
Reduces visible muzzle flash, helping preserve night vision and reduce distraction, especially in low-light shooting.
Directs gases upward and to the sides (with closed bottom, if timed correctly) to help slightly mitigate dust signature when shooting prone.
Protects the barrel crown from impacts and nicks, which can otherwise degrade accuracy.
For defensive rifles, training carbines, and range guns, a properly installed A2 flash hider is a reliable, no-nonsense choice that just works.
Standard 1/2x28 Threads – Easy Fit on Most AR Barrels
Threaded 1/2x28, this flash hider is ready to install on the vast majority of AR-15 pattern 5.56 barrels:
Compatible with 16" carbines, 14.5" (with pin/weld), and other lengths that use 1/2x28 muzzle threads.
Works with both .223 Wylde and 5.56 NATO chambers as long as the barrel is threaded 1/2x28.
Typically installed using a crush washer or shim set (not always included; check your specific listing or kit contents).
Whether you’re building from the ground up or refreshing an older upper, this Anderson part is a drop-in, gunsmith-friendly solution.
Anderson Quality – Great for Budget Builds & Workhorse Rifles
Anderson Manufacturing is known for offering solid, mil-spec parts at value pricing, and this A2 flash hider fits that philosophy perfectly:
All-steel construction for durability and heat resistance.
Tough, protective finish (typically a black phosphate or similar coating) that resists corrosion and blends with most AR barrels and front sights.
Backed by Anderson’s reputation as a major supplier of AR receivers, parts, and complete rifles used by builders nationwide.
If you’re assembling a budget-friendly rifle, a training gun, or a fleet of patrol carbines, this flash hider gives you dependable performance without unnecessary cost.
