Overview
The Battle Arms Development Enhanced 9mm Blowback BCG uses a MilSpec 8620 heat-treated steel carrier with a hard nitride black finish. It weighs 14.9 ounces, works with Glock- and Colt-pattern magazines, and has a removable carrier weight. Battle Arms Development lists it as full-auto compatible.
Its external AR-15 style extractor uses an O-ring and spring. A standard firing pin cotter pin retains the reinforced firing pin. The ramped bottom geometry supports broad trigger compatibility, and the charging handle bears on the carrier body instead of the carrier key.
