  • Description

    Ruger AR-556 Model 8500 Flat Top AR-15 Rifle


    • The milled gas block is located at a carbine length (M4) position for improved balance and handling. Multiple attachment points include a QD socket and bayonet lug, for many sling and accessory mounting options. Serrations on the angled face of the gas block provide a low glare surface.
    • The handguards are made from heat-resistant glass-filled nylon for shooting comfort and durability.
    • The front sight post is elevation adjustable, and a front sight tool is included. The A-2 Style F-Height allows co-witness with many optics. The Ruger® Rapid Deploy folding rear sight provides windage adjustability and is a solid, reliable aiming system when coupled with the elevation adjustable front sight. The rear sight can be folded out of the way to make room for optics but can be instantly redeployed if needed.
    • The six-position telescoping M4-style buttstock and Mil-Spec buffer tube allow the rifle to be properly sized for different shooters, or varying levels of outerwear or defensive gear.
    • The 16.1 inch medium contour barrel is cold hammer-forged providing ultra-precise rifling for exceptional accuracy, longevity and easy cleaning. The 1:8 twist rate stabilizes bullets from 35 to 77 grains and the 5.56 NATO chamber allows the use of both 5.56 NATO and .223 Rem. ammunition. M4 feed ramps provide improved operational reliability and the matte black oxide finish reduces glare and provides corrosion resistance. A Ruger® flash suppressor is provided and the ½"-28 threaded barrel allows for standard muzzle accessories to be installed.
    • The ergonomic pistol grip features an extended trigger reach for more precise trigger control. The enlarged trigger guard is designed to allow for gloved shooting.
    • The chrome-plated bolt carrier inside diameter and chrome-plated gas key inside diameter provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing. A matte black oxide finish on the exterior of the bolt carrier provides corrosion resistance.

    Mine arrived today. Ran 200 rounds through it, like a hot knife through butter. Can't beat the $499 price, can't beat the Ruger quality, and no one can touch Ruger's customer service. This joins my Mark III, 10/22 Takedown, and SR1911 in .45ACP in my Ruger collection. Don't hesitate to by the AR-556, especially at the sale price. You won't be disappointed! Thank you Centerfire for a great sale.
    Received the rifle today. Outta the box...gonna give it 5-stars...great looking gun. Plan on running a few mags thru it this it runs like a champ. If not, expect an update. At $499, this was a no-brainer...for me anyway. I've seen these 556's range in price from $499 to $679, all online, mind you. Funny thing, my FFL said his cost for these were $540+. Better jump on these while available. Thumbs up to Centerfire Systems...Thank you.
