Description
Maxim Defense PDX Features The Maxim Defense PDX chambered in .300 Blackout is born from the SOCOM PDW solicitation purpose-engineered to handle the fierce demands of Tier 1 operations with a material composition of 6Al-4V titanium 17-4 stainless steel and 7075 and 6061 aluminum delivering exceptional durability and a strength-to-weight ratio that outperforms standard aluminum-only AR-platform builds. The 5.5 barrel is threaded 5/8x24 and ships with a Hate Brake installed providing immediate muzzle device compatibility and suppressor-ready threading for .300 Blackout cans without additional adapters. Hard anodizing across the aluminum components provides long-term corrosion and wear resistance through the abrasive demands of close-quarters training and field use. For special operations community members law enforcement professionals and serious AR pistol builders who demand a subcompact .300 Blackout platform built to military-derived standards the PDX s material stack and construction quality set it apart from conventional AR pistol offerings. The Maxim SCW Pistol System brace delivers a compact stable shooting interface that keeps the PDX s 18.75 overall length as small as possible while providing a comfortable controlled platform for rapid close-quarters engagement. A CQG grip and flat-top optics-ready receiver with Picatinny rail provide familiar AR ergonomics and broad optics compatibility for red dots holographic sights and magnified optics without modification. At 5 lbs 11 oz the PDX remains light enough for one-handed manipulation and extended carry while the .300 Blackout cartridge delivers maximum energy on target at close-quarters distances with both supersonic and subsonic loads. One 20-round magazine is included for immediate use. For home defense users suppressor owners and .300 Blackout platform enthusiasts who want a SOCOM-derived subcompact pistol with premium materials and proven close-quarters capability the Maxim Defense PDX is for sale at ARMSAGORA and delivers that Tier 1-inspired performance in Flat Dark Earth.
