➲ Colt Competition Style Barrel

The barrel is one of the few components that directly affect the accuracy and weight of your build.  This barrel has a nitride finish for increased strength and durability. While featuring a special contour that is designed to be lighter than a conventual SOCOM barrel giving you that extra edge when shooting 3-gun competitions. This barrel offers a 1:8 twist rate, suitable for both heavy and light ammunition.  It is corrosion resistant resulting in an extended barrel life that is longer than conventional chrome lining. Thus, being the perfect barrel for long distance shooting, competitions, hunting and practically any shooting application you’ll subject your AR-15 too.

➲ A2 Flash Hider

The muzzle device is designed to perform a specific task, like suppress flash intensity or reduce felt recoil. This A2 Flash Hider is machined from quality steel and finished with an exceptionally corrosion resistant salt bath nitride for a lifetime of service. It provides effective flash suppression that preserves the shooters night vision by disrupting the muzzle flash when firing in low light conditions. While its closed bottom with top and side ports offers reduced dust signature when shooting from the prone position while additionally acting as a compensator.

    Recently purchased this upper, and all I can say is WOW! The assembly is spot on, and love the keymod forearm. After sighting in @ 100 yds, able to shoot 1.25 inch group.

    Can’t beat the deal with a stick. Ordered and arrived to my door within five days. Flawless on inspection after opening. No blemishes or scratches. Very light and put together well with no need for additional torquing or other adjustments. Dropped right into Anderson lower with no trouble. Used with CBC Industries BCG and CH that was on sale for $69. Ran through 100+ rounds without additional lubrication with no feeding or cycling issues.At the range it shot very well. Paired with a Vortex Strikefire II red dot, I was shooting sub-inch groups at 50 yards with three different rounds at 55 and 62 grains. Very confident that this upper/barrel combination will shoot inch groups with a good scope at 100 yards and further.
