.308 Caliber AR type Upper half with 20" inch Heavy barrel and A3 Upper receiver.  This 7.62x51mm cal barrel is 20" long, threaded the standard 1/2 x 28 tpi, and has an A2 flash hider with the correct crush washer. The barrel has a four position gas block for easy mounting of accessories. It sports rifle length handguards with full heat shields, and a correctly sized gas port for reliable function in full or semi auto. The barrel is machined from chrome-moly, high vanadium steel and hardened to a U.S. government Mil-spec of Rc 26-32. The barrel, and all external steel parts, are manganese phosphate finished IAW 5.3.1.2 of Mil-STD-171, the U. S. government's recommended protective finish for steel. This finish not only looks great, it affords complete corrosion protection. These barrels are of heavy-weight ( .750 under the front sight base) dimension which alleviates barrel whip and enhances accuracy in semi auto fire and helps dissipate the heat of full auto fire. The barrel is button rifled with 6 grooves, right hand, 1 / 10" twist. The 1/10” twist is best because it handles the widest variety of ammunition and bullet weights.

The barrel is mounted on a BILLET A3 upper receiver with built in Mil-spec M1913 Picatinny accessory rail, hardcoat anodized IAW Mil Spec A8625, Type III, Class II, black per No. 37038, Table IX with nickel acetate seal, and barrel nut threads as per the Mil-spec with mil spec threads. This upper receiver is complete less bolt/carrier assembly and charging handle. The upper is fully assembled. Drop in your bolt/carrier and charging handle, check headspace and let her rip! 

Add $50 for CHROME LINED barrel and chamber, Add a BOLT CARRIER GROUP if you need one. (You must ACTUALLY Order part # AR-CHROME for chrome or the BOLT CARRIER GROUP on your web order form, if you do not see it on your form, you have not ordered it and will not receive a chrome lined barrel or BCG. Do NOT just put it in the special instructions). This upper is for DPMS or compatible lowers.
