Maxim Defense PDX 505-SPS Pistol, 7.62x39mm, 5.5-Inch, Urban Grey

The Maxim Defense PDX 505-SPS (Maxim part no. MXM50840) delivers the same reliability-enhancing technology shooters expect from Maxim’s PDX line, chambered in 7.62x39mm with a compact 5.5-inch barrel. Where the standard PDX uses Maxim’s SCW stock or brace, the 505-SPS features the SCW Pistol System instead, the company’s most streamlined option for the back end of an AR pistol. At just 5.3 ounces, the SCW Pistol System shaves over 10 ounces compared to the SCW stock, with no protruding angles or snag points. It includes a rear single-point QD swivel mount, ideal for sling placement on accuracy-aiding shots downrange. Finished in urban grey by Maxim Defense Industries, this pistol pairs classic 7.62x39mm ballistics with a genuinely streamlined build.
