ALWAYS ARMED 16" UPPER RECEIVER WITH 12" RAIL COMBO DEAL - 5.56 NATO/.300 BLACKOUT

Always Armed 16" Upper Receiver with 12" Rail Combo Deal - 5.56 NATO & .300 Blackout

Get double the versatility for your AR-15 platform with the Always Armed 16" Upper Receiver with 12" Rail Combo Deal. This bundle includes two complete, factory-assembled upper receivers—one chambered in 5.56 NATO and one chambered in .300 AAC Blackout—allowing you to easily swap between multi-purpose target shooting and high-velocity suppression performance using a single lower receiver.

Precision-manufactured in the USA, both complete upper groups feature forged Mil-Spec 7075-T6 aluminum upper receivers finished in durable hard-coat black anodizing. Each unit is equipped with a 16" 4150 steel barrel with a corrosion-resistant black nitride finish, an A2 flash hider, and a 12" Free-Float M-LOK Handguard for modular accessory attachment. The 5.56 NATO upper utilizes a smooth carbine-length gas system with a 1:7 twist rate, while the .300 Blackout upper incorporates a pistol-length gas system with a 1:8 twist rate engineered for optimal cycling with subsonic or supersonic loads.
