Sturm, Ruger & Co., Inc. has been one of the nation's leading manufacturers of dependable rifles, shotguns, and pistols since 1949.

The Ruger AR-556 is Ruger's response to the flood of 'me too!' AR-15 rifles that have come onto the market in the last couple of years. Where most of those rifles are carbon copies with a new name, the AR-556 offers a few improvements. As an added bonus, it is ready to roll out of the box, fully equipped with quality furniture and sights.

For shooters who like to tinker, Ruger has replaced the traditional barrel nut and delta ring assembly with their new patent pending design. Where a standard delta ring assembly can sometimes feel like you need three hands to remove or install the handguards, Ruger's system allows for fast and easy removal or installation. Whether upgrading your furniture or simply doing a deep clean, this is a great bonus. The lightweight Magpul MOE M-LOK handguards are ergonomic and modular, allowing users to mount their favorite M-LOK accessories at the 10, 12, 2, and 9 o'clock positions. An integral handstop prevents shooters from accidentally touching the A2-style F-height front sight block, while an integral heat shield keeps your hands cool even under extended firing strings.

The cold hammer forged 4140 chrome moly steel barrel has precise 1:8 twist rifling, well suited to the wide variety of bullet weighs available on the market today, while providing exceptional accuracy. The low-glare black oxide finish also provides excellent corrosion resistance. The F-marked front sight block is the perfect height for a carbine-length gas system, especially when combined with Ruger's Rapid Deploy folding rear sight. When running optics, the rear sight can be folded out of the way, but deployed in an instant if needed. For enhanced reliability, the bolt carrier group is internally chrome lined for reduced carbon build up and easier cleaning.

Whether you're looking for your first AR-15, or simply want an improvement on the tried and true M4-style in your collection, the AR-556 is an excellent option.
