The flat top M4 Mil-Spec upper receiver is 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.
The barrel is made from the most durable material in the barrel world, 4150 Chrome Moly Steel! These barrels are NOT chromed lined because that reduces accuracy, it features Nitride Coating to increase durability and reduces wear & tear! It features a gas impingement system operating at the pistol length & a 1:8 twist. Nothing is overlooked on this barrel, it is even head spaced twice from the manufacturer for reliability!
The 12” Unmarked Keymod by Hera is engineered and manufactured in Germany. This modernly designed rail is made from Airplane grade Aluminum! The rails are then hard coat anodized to improve the strength! To top it off, Hera’s “Anti-Turning Milling” eliminates turning.
As everyone knows, CBC Industries assembles there uppers exclusively with Veterans of our Armed Services!
