This AR-15 upper assembly is made from the highest quality material found in the AR world, the rails is engineered and manufactured in Germany and the rest of the components are made in the USA! This upper is assembled in Charleston, SC by CBC Industries, a company synonymous with high-quality material, meticulous workmanship & incredible prices.
The integrity of the upper assembly starts with the upper receiver and CBC spared no expense! The flat top M4 Mil-Spec upper receiver are forged CNC Machined from 7075-T6 Aluminum, the hardest and most durable material of any upper! To ensure even more strength they are Mil-Spec Type 3 hard coat anodized in rugged black. These are heavy barreled uppers.
The upper has a 6 groove 16” barrel chambered in 5.56x45 and features a 1:8 twist. This 5.56 barrel can achieve a 1” grouping at 100 yards with US made match grade ammo and properly matched bullet grain weight to twist rate. The barrel is made from the most durable material in the barrel world, 4150 Chrome Molly Steel! These barrels are NOT chromed lined because that reduces accuracy, it features Nitride Coating to increase durability and reduces wear & tear! The MOD features a gas impingement system operating at the carbine length. Nothing is overlooked on this barrel, it is even head spaced twice from the manufacturer for reliability!
The 12” Keymod by Hera is engineered and manufactured in Germany. This modern designed rail is made from Airplane grade Aluminum, extruded with the most accurate machines in Germany and CNC milled with computer accuracy! The rails are then hard coat anodized to improve the strength, these rails are known as the “Fort Knox” of handguards! The rail is attached to its own barrel nut by clamp mounting with 3 screws. To top it off, Hera’s “Anti-Turning Milling” eliminates turning of the rail so your scope is always zeroed in!
What sets these apart from the rest is CBC uses a lapping tool that is coated with a compound and attached to a standard drill for approximately 10 minutes, taking the natural beveled edge and flatting the surface. Blue Loctite is then placed on the barrel extension and spread evenly on the extension. The barrel and receiver are then placed together and the barrel nut is torqued on. It is then left on a flat surface for 24 hours to allow the liquid to cure. This unique process takes the beveled receiver end and flattens it so it becomes more flush with the barrel nut ring. This ensures a more accurate alignment, in turn making a more accurate shot.
As everyone knows, CBC Industries assembles there uppers exclusively with Veterans of our Armed Services! These military men have a found place in their heart for the 5.56 MOD, so they mic port holes, torque to military specs and double & triple check the quality checklist. The end result, the highest quality upper assemblies for the money in the market made right here in the United States!
