Maxim Defense PDX Pistol, 7.62x39mm, 5.5-Inch, Arid

The Maxim Defense PDX Pistol (brand part no. MXM-47800) is engineered for Tier 1-style close-quarters applications, measuring just 18.75 inches overall in its Arid cerakote finish. At the heart of the PDX is Maxim’s patented SCW system, a 4-inch brace with an integrated bolt carrier group and interchangeable buffer weights, giving shooters enhanced recoil control, faster follow-up shots, and improved reliability. Chambered in 7.62x39mm with a 5.5-inch barrel, the PDX ships standard with the Maxim HATEBRAKE muzzle booster, installed under the handguard to reduce recoil, cut flash signature, and redirect blast forward, ideal for close-quarters or suppressed use. It’s one of the most purpose-built PDW-style pistols in the AR pistols lineup from Maxim Defense.
