A full-length Picatinny rail runs continuously over the free-float aluminum M-LOK handguard, which provides mounting slots at 3, 6, and 9 o'clock. The platform is configured without sights.
Controls include an AR-style ambidextrous charging handle and a manual safety. The carbine uses an alloy receiver finished in matte black, matched by the overall matte black finish.
The adjustable stock with rubber buttpad supports a comfortable fit. Maximum capacity is 35+1, and this example includes both extended 35-round and standard-length 20-round proprietary MPX translucent polymer magazines with steel feed lips.
