AR-15 Ruger AR556 Firearms Review

The Ruger AR556 chambered in 5.56 NATO is nothing short of exceptional.

From its robust construction to its precision engineering, this rifle sets the bar high for firearm enthusiasts.

Starting with the build, the rifle offers a solid set of materials and craftsmanship. The 7075-T6 hard-coat anodized aluminum forgings ensure durability and longevity. Paired with a shot-peened and proof-tested 9310 steel bolt and an 8620 steel bolt carrier, you've got a firearm built to last. The chrome-plated inside diameter of the carrier and gas key, guarantee reliability over countless rounds.

What truly sets this AR556 apart is its thoughtful design. The Ruger Rapid Deploy folding rear sight, with windage adjustability, pairs seamlessly with the A2-style, F-height front sight. This duo creates a rock-solid aiming system, ensuring precision and accuracy in every shot. The gas block's M4 positioning enhances balance and handling, while multiple attachment points offer versatile sling and accessory mounting options.


The heat-resistant glass-filled nylon handguards provide shooting comfort and durability, and the single-stage trigger delivers consistent fire control. The enlarged trigger guard accommodates gloved shooting in cold weather. All of my ARs have enlarged or oversized trigger guards installed. A great upgrade right out of the box, a testament to Ruger's attention to detail.

Ruger's AR556 Offers A Premium Cold Hammer Forged Barrel. 

The medium contour, cold hammer-forged alloy barrel with 1:8" twist rifling guarantees exceptional accuracy across a wide range of bullet weights. An absolutely premium offering from Ruger out of the box. This rifle's ability to accommodate both 5.56 NATO and .223 Rem. ammunition adds versatility to your shooting experience. The matte black oxide finish on the barrel and Ruger flash suppressor minimizes glare and enhances corrosion resistance.


The inclusion of a 30-round Magpul PMAG magazine is a nice touch, rounding out the package. But it doesn't stop there; the ergonomic pistol grip and six-position, telescoping M4-style buttstock make this rifle adaptable to shooters of all sizes and varying outerwear.


Lastly, the aerospace-grade 7075-T6 aluminum forging of the flat top upper receiver, featuring a forward assist, dust cover, and brass deflector, ensures that the Ruger AR556 is ready for whatever challenges you throw its way.


Ruger's AR556 chambered in 5.56 NATO is a seemingly mil-spec firearm with great out of the box components. Its exceptional build quality, precision aiming system, and versatile design make it a top choice for enthusiasts, whether you're at the range or out in the field. Ruger has once again proven their commitment to quality and innovation with this outstanding rifle.
