Hidden Gem (NBS) Barrel
11.5" 5.56 NATO 1:7 Twist 4150V Black Nitride Carbine Barrel - 1101-0201-003 sold under NBS brand... who originally made this barrel before being labeled an NBS brand to be sold under? AI Response: - Most NBS barrels in this spec range are sourced from Rosco Manufacturing or Ballistic Advantage. - Both companies produce 4150 CMV (sometimes listed as 4150V) nitride barrels in 11.5" carbine gas, 1:7 twist — and both are known OEM suppliers for house brands. - Rosco in particular has a reputation for supplying “white label” barrels to resellers, and their 11.5" nitride carbine barrel matches the NBS spec sheet almost exactly. Most Probable Answer The NBS 11.5" 5.56 NATO 4150V Black Nitride Carbine Barrel (SKU 1101-0201-003) was originally manufactured by Rosco Manufacturing, then rebranded under the NBS label for sale through AR15Discounts. Ballistic Advantage is another possible source, but Rosco is the most consistent OEM behind NBS-branded barrels in this configuration.
