Maxim Defense SDX-508 .300 Blk SBR with Maxim DSX-D Suppressor 8.5" Barrel - Arid FDE

Engineered to conquer the world’s most rigorous tactical demands, the Maxim Defense SDX-508 is a premier tier-one Short Barreled Rifle (SBR) chambered in the devastating .300 Blackout. Measuring just 28.125 inches in overall length, this ultra-compact platform seamlessly integrates an 8.5-inch threaded barrel with the included, heavy-duty DSX-D Suppressor. Finished in a rugged Arid (Flat Dark Earth) Cerakote, the SDX-508 delivers unmatched maneuverability, stealth, and terminal performance, making it the ultimate suppressed weapon system for elite operators and dedicated professionals.

The crown jewel of the SDX-508 is its included DSX-D Suppressor system. Forged from an indestructible blend of 6Al-4V Titanium and 17-4 Stainless Steel, and coated in advanced DLC and Type III Hard Coat Anodizing, this suppressor is designed to be the most robust in its class. Repeatedly subjected to brutal SOCOM testing tables across various calibers, it survives without damage or degradation in sound reduction. Paired with Maxim's highly coveted Gen 7 CQB Stock, this platform not only drastically cuts acoustic signature and felt recoil but actively enhances accuracy during high-speed, close-quarters engagements.
