Wraithworks WARSCORP9 Roller Delayed Side-Charging AR Pistol – Black | 9mm | 8.5″ Barrel | 7″ M-LOK Rail | SB Tactical HBPDW Brace | Accepts Scorpion Mags

The Wraithworks WARSCORP9-BLK-MRDB is a USA-made, roller-delayed 9mm AR pistol built around the proven WARSCORP9 platform and designed to accept CZ Scorpion Evo-compatible 9mm magazines. This premium WARSCORP9 configuration features a machined billet upper and lower receiver set, 8.5″ nitride-treated 9mm barrel, 7″ 6061-T6 M-LOK handguard, nitrided 9mm bolt, AR-compatible fire control layout, and a factory-installed SB Tactical HBPDW brace. The major upgrade on this model is Maxim Defense’s Roller Delayed Buffer system. The Maxim RDB system is designed to transform a 9mm AR-pattern firearm into a roller-delayed blowback system, helping reduce felt recoil, increase reliability, and minimize friction for enhanced performance. By allowing gas pressure to stabilize before extraction, the system helps deliver smoother operation compared to a standard direct-blowback 9mm AR buffer system. The Maxim Defense RDB system is not full-auto rated. The factory-installed SB Tactical HBPDW brace gives this model a compact, premium PDW-style profile. The HBPDW is a low-profile, 3-position adjustable pistol stabilizing brace with an integral ambidextrous QD sling socket. It provides a shorter, more streamlined brace package while maintaining improved stabilization and control. The WARSCORP9 lower receiver is fully ambidextrous and includes ambidextrous safety controls, ambidextrous bolt catch levers, ambidextrous magazine release buttons, and a paddle-style magazine release. The paddle release and magazine release buttons are designed to be reachable from the pistol grip hand, giving AR users familiar controls with added functionality. The 8.5″ 4150 chrome moly barrel features a 1:10 twist, nitride finish, and 1/2×28 threads, paired with a Wraithworks custom 9mm muzzle device. The 7″ 6061-T6 M-LOK handguard keeps the front end compact while offering accessory mounting space. This model includes two 35-round Magpul CZ Scorpion Evo-compatible magazines, model MAG1013-BLK. Aluminum components are finished in durable Mil-Spec Type III Class 2 hardcoat anodizing, and the pistol is designed, manufactured, and assembled in the USA. The WARSCORP9-BLK-MRDB is the premium 9mm WARSCORP9 configuration for dealers and end users who want Scorpion-mag compatibility, side-charging AR ergonomics, a compact HBPDW brace package, and the smoother shooting impulse of the Maxim Defense Roller Delayed Buffer system.
