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 in rugged black.
This Classic SBR features a 10.5” 5.56 barrel made of the best barrel material known to man, 4150 Chrome Moly steel! This SBR has a 1:7 twist rate, pistol gas system and head spaced twice from the US manufacturer. This barrel is incredibly accurate and durable, the strength comes from the 4150 CM steel and the Nitride coating!
The rail is engineered and manufactured in Germany. The 9” Hera IRS Quad Float rail’s design is a classic Picatinny handguard. It is made from Airplane grade Aluminum then CNC milled! The rails are then hard coat anodized to improve the strength!

Other configurations may violate Federal law. Installation of AR-15 upper assemblies with certain features including, but not limited to: flash hiders, bayonet lugs, and threaded muzzles may violate state and/or local laws.

    This is my second upper from CBC and second blemished up at that and I must say I’m impressed yet again. For a blemished upper you would be hard pressed to find anything wrong with these. There are no T marks but honestly who cares just make your own and if it does have a few blem here and there just paint it like a high speed American that you are. I don’t buy or build guns for show room plunker guns. They get dirty get scratched and get used. Love the 10.5” size my only request by CBC would to have a 10.5 upper with maybe a 10” hand guard so if you decided to suppress it or toss a muzzle device on there it would be tucked into the rail. Would rec buying 100%
