Description

Complete AR-15 Piston Upper 223 Rem 14.5″ 41V45 Steel Heavy Contour

The SR-556 Upper Receiver comes from the factory with a plethora of parts
that are popular aftermarket add-ons to the traditional AR platform. These
uppers feature an adjustable two stage gas piston system that significantly
reduces the amount of fouling introduced to the receiver. The piston and
gas tube are both hard chromed to ensure long life and reliability. In fact
chrome seems to be a common thread with the SR-556 upper. The bolt carrier,
gas regulator, and barrel (hammer forged in-house from Mil-Spec 41V45) are
all chromed. The barrel is available threaded or with permanent flash
hider. Also featuring folding detachable iron sights, and quad rail forearm.Category : UppersType : Complete Piston OperatedCaliber : 223 Remington/5.56 NATOSights : Flip UpBarrel Length : 14.5″ w/Fixed BrakeBarrel Material : 41V45 SteelTwist : 1:9Barrel Description : Heavy ContourBarrel Finish : BlackReceiver Description : A3Receiver Finish : Black
