Ruger has recently announced the expansion of their popular AR-556 series of rifles with the new chamebering of 300 blackout.

The 300 Blackout has become a pretty standard cartridge in the AR-15 pattern.

It is only natural progression for Ruger to support the 300BLK cartridge in their AR-15 series.

KEY FEATURES:

+ 11″ aluminum handguard is free-floated for accuracy and features Magpul® M-LOK® accessory attachment slots along the 3:00, 6:00 and 9:00 positions with additional slots on the angled faces near the muzzle.

+ Flat top upper receiver features a Picatinny rail for easy attachment of magnified optic, red dot or open sights.

+ Made from 7075-T6 hard-coat anodized aluminum forgings, shot-peened and proof-tested 9310 steel bolt, and 8620 steel bolt carrier. The inside diameter of the carrier and gas key are chrome plated and the key is staked for longevity.

+ Single-stage trigger provides durable and reliable fire control. The enlarged trigger guard is designed to allow gloved shooting in cold weather.

+ 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.

+ Equipped with a heavy-contour, cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning. M4 feed ramps provide improved reliability, and the matte black oxide finish reduces glare and provides corrosion resistance.

+ Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver features a forward assist, dust cover and brass deflector.
