[STRATOS-X] MPX 3.5inch COPPERHEAD GBBR Gas Blowback Rifle Black JP Ver./Real Marking (New release in May 2026)

The SIG MPX Copperhead (3.5 inch) is an ultra-compact 9mm Personal Defense Weapon (PDW) developed by SIG. Featuring the shortest 3.5-inch barrel in the MPX series, it is designed as a model that prioritizes extremely high portability and operability.

It utilizes a short-stroke gas piston system and a rotating bolt, and its AR-style controls offer high reliability and ease of use. It also features an ambidextrous selector, magazine release, bolt release, and charging handle, making it easy for both left and right-handed shooters to operate.

The monolithic upper receiver prioritizes compactness, which limits expandability such as handguard replacement, but significantly reduces its size and weight.

Models equipped with a stabilizing brace are foldable and extendable, making them highly suitable for close-quarters applications such as in-vehicle use or carrying in a bag. Since it uses 9mm ammunition, recoil is relatively light, and while muzzle flash is significant, it offers excellent handling and controllability at close range.

This model represents the most extreme pursuit of the MPX series' "more than a handgun, less than a rifle" balance, and is particularly popular among users who prioritize close-quarters defense, tactical applications, and portability.
