The Copperhead configuration centers on an ultra-short 3.5 inch carbon steel barrel with a 1:10 twist, delivering a highly compact 9mm package. Its closed-bolt, short-stroke gas piston system is purpose-built for reliable operation in a micro format.
The monolithic upper receiver provides a continuous 12 o'clock Picatinny rail for mounting accessories, while the rear of the receiver integrates a 1913 Picatinny endcap/interface. The right-side ejection port is cleanly executed without a dust cover.
Controls follow the AR pattern for familiarity and efficiency. An ambidextrous safety is standard, complemented by an AR-style charging handle, a left-side bolt catch, and a distinct right-side bolt release.
The alloy receivers wear a factory Coyote Tan Cerakote finish. The pistol uses SIG MPX detachable box magazines, and this example includes four 35-round OEM polymer mags for a stated capacity of up to 35+1. A folding rear backup sight is installed from the factory.
Made in the USA, this MPX Copperhead offers a compact footprint with thoughtful ergonomics, including a SIG polymer pistol grip, ready for a wide range of 9mm roles.
