Product Spotlight: B5 Systems Retro Carbine Stock
This video features a product spotlight on the B5 Systems Retro Carbine Stock (RCS). The presenter highlights its ability to replicate the classic look of 1960s CAR-15 XM177 carbines and early M4 Carbines, making it ideal for retro AR-15 builds. The stock is constructed from modern, lightweight, reinforced polymer for durability, while maintaining the limited feature set of originals, including specific texturing, sling loop and slot, and the adjustment lever. Notably, it lacks the side reinforcement ribs found on later M4 stocks, ensuring its authentic appearance for period-correct builds. The RCS is presented as a practical solution for those seeking vintage aesthetics, preserving scarce originals, or desiring a compact and lightweight stock.
