AR-15 Uppers are made with forged front sight base (not cast), A-2 sight post (not A-1), sling swivel rivet (not roll pin), heat shields in hand guards (A-2 and CAR), Military contract upper,  carrier assemblies,  and charging handles. These uppers include Colt fi contract  delta rings, and gas tubes.  All barrels are bored to 5.56mm for use with either .223 caliber or 5.56mm ammo.  We use 1x9 twist, chrome moly match Hbar barrels (standard, unless specified) and stainless steel 1 in 8" or 1 in 10" barrels for our bull barreled uppers. We can have your Bull Barreled upper coated and have many options available.  We can also customize your order with a wide selection of barrels and parts available from various manufacturers.  Please call or send us an e-mail if you do not see the configuration that suits you.

This AR-15 barreled upper is headspaced, and ready to mount to your lower receiver after installing the bolt carrier group, see options.  Once you have an assembled lower with the parts installed and mount the upper,  this is an operational firearm 5.56mm.
