Ruger AR-556 | .300 AAC Blackout | 16.1″ | 30rd | 8530

The Ruger AR-556 is a modern sporting rifle chambered in .300 AAC Blackout that combines forged 7075-T6 receivers with a heavy-contour, cold hammer-forged barrel. It ships with an 11″ free-float Magpul M-LOK handguard, a six-position telescoping M4-style stock, and one 30‑round metal magazine. For a versatile optic under $1,000 that complements this platform, consider a 1-6x or 1-8x low-power variable optic such as the Vortex Strike Eagle 1-6x for close-to-mid-range utility.

Typical applications include short-range precision shooting and hunting in brush or wooded terrain where .300 BLK performs efficiently; it is also suitable for suppressed accuracy work when paired with compatible suppressors and subsonic ammunition.
