Complete AR-15 Flat Top Upper .223 / 5.56 caliber for AR-15 rifle. Ready to drop in and push pin on AR lower.The .223 Wylde Chambering allows the upper to properly feed and fire both 5.56 NATO and .223 Remington. 1 in 9 twist rate.
These are really nice, function tested, and ready to drop in to any AR-15 lower and start firing... Upper is machined from 7075-T6 forgings that are hard coat anodized for wear and scratch resistance meeting MIL SPEC. Barrels drilled, reamed and buttoned from 4140, 4150 Chrome Moly, Chrome Moly Vanadium per MIL –B-11595E or 416 stainless gun quality steel then stress relieved prior to contouring and chambering. Twist rate is 1 in 9. The barrels are chambered in the highly desireable .223 Wylde and therefore chambered for and suitable for firing either the Nato 5.56 designation or the .223 Remington commercial round. The head space is set and the barrel is tested for straightness using a 6” drop pin gage. The steel barrel assemblies are Parkerized to eliminate rusting. Bolts machined from tool steel, hardened and tempered to provide maximum wear characteristics then Parkerized to eliminate rusting. Bolt carriers machined from 8620 gun quality steel, heat treated and tempered to maximize strength and wear characteristics then Parkerized to eliminate rusting. These work great with our complete lowers...
The barrels on these are made from 4140 cold rolled steel and are rated at a barrel life of approximately 150,000 rounds. They are very top end. They are not chrome lined as most AR-'s are not. Chrome lining on modern rifles is typically used where there is a high probability of corrosive ammo being used such as AK type rifles chambered for foreign calibers. Since chrome lining may slightly affect accuracy, and since most AR-15 rifles are designed with accuracy as a benchmark, and since virtually all .223 / 5.56 NATO is non corrosive...most AR manufacturers do not chrome line barrels. * No FFL required on the uppers as they are not the serial numbered part and not considered a firearm. These can ship directly to the end user.
