Description

Maxim Defense PDX Features The Maxim Defense PDX chambered in 5.56 NATO is built from 6Al-4V titanium 17-4 stainless steel and 7075 and 6061 aluminum delivering a strength-to-weight ratio that outperforms standard aluminum-only AR builds in a SOCOM PDW-inspired subcompact platform. The 5.5 barrel ships with a Maxim Hate Brake that reduces recoil minimizes flash signature and directs gas and the concussion wave downrange for improved shooter control and comfort during rapid fire in close-quarters environments. An integrated BCG with interchangeable buffer weights allows the system to be tuned for optimal reliability and performance across different ammunition types and suppressor configurations. The patented Maxim SCW collapsible stock system cuts the stock length to just 4 keeping the PDX at 18.75 overall for maximum maneuverability in confined spaces and vehicle-based applications while the Arid Brown finish across the aluminum receiver polymer grip and synthetic stock provides a cohesive tactical aesthetic. At 5.10 lbs with an optic-ready configuration and one 20-round magazine included the PDX arrives as a complete professional-grade sub-compact personal defense platform. For home defense users law enforcement professionals and 5.56 NATO enthusiasts who want a SOCOM-derived subcompact pistol with premium materials and Hate Brake performance in Arid Brown the Maxim Defense PDX is for sale at ARMSAGORA and delivers that Tier 1-inspired performance out of the box.
