The BCM complete lower receiver with MK2 receiver extension and SOPMOD wide-body Mod 1 stock in Flat Dark Earth (brand part no. BCMLRG-RMS-STK-MOD-1-SPMD-FDE-COSMO) is a factory blem unit, meaning it ships fully assembled and functionally identical to Bravo Company Mfg‘s standard complete lower but carries a cosmetic finish flaw that doesn’t affect performance. This lower uses BCM’s MK2 receiver extension, roughly 3/4 of an inch longer than a standard 6-position extension, paired with the wide-body SOPMOD Mod 1 stock. Choosing a factory blem is a way to get the same BCM build quality at a value price when a cosmetic imperfection doesn’t matter to the builder. Among the complete lowers in the AR15 lowers category, this factory blem lower is a fit for builders prioritizing function over a flawless finish.
