The Ruger AR-556 in the Custom Marble Distressed finish is a semi-automatic rifle chambered for 5.56mm NATO with a 16.10″ cold hammer-forged barrel and a 30-round magazine. For close-to-mid range use, a Vortex Strike Eagle 1-6×24 pairs well with this platform and remains priced under $1,000 while co-witnessing with the A2-style front sight.
