Wraithworks WARMP45 Radial Delay Side-charging AR Pistol - Black .45ACP 8" Barrel 7" M-LOK Rail SBA3 Brace Accepts UMP-45 Mags

The Wraithworks WARMP45 is a purpose-built .45 ACP radial delayed AR pistol designed to combine the proven AR platform with the rugged reliability and appeal of the UMP-45 magazine system. Designed for smooth shooting and reduced recoil compared to traditional blowback PCCs. Built around a machined billet upper and lower receiver set, the WARMP45 features a side-charging configuration and a fully ambidextrous lower, including ambi safety, bolt catch, and magazine release system. Controls are intuitive and easily operated from the firing hand, making it familiar for any AR user while offering enhanced functionality. The platform is equipped with the Wraithworks Ambidextrous 50/90 Safety Kit, allowing the user to configure either a 50-degree short throw or standard 90-degree throw. Multiple included paddle options allow the safety to be tailored to individual preference, using durable Torx hardware and backed by a lifetime warranty. The radial delayed blowback system helps reduce felt recoil and improve shootability compared to traditional blowback PCCs, making it a strong option in the growing pistol-caliber/subgun category. Up front, the WARMP45 is equipped with an 8" 4140 chrome moly barrel with nitride finish, 1:16 twist, and .578×28 threads, paired with a 2-port muzzle compensator for added control. The compact 7" M-LOK handguard provides ample mounting space while maintaining a streamlined profile. The pistol is finished with an SB Tactical SBA3 adjustable brace, a Nickel Teflon 5.5 lb trigger, and the Wraithworks ATG adjustable grip with three selectable angles for improved ergonomics. Weighing just 5 lbs 3 oz unloaded, the WARMP45 is built for maneuverability while maintaining durability with Mil-Spec Type III hardcoat anodized aluminum components. This platform is fully compatible with many standard AR-15 components, including trigger groups, furniture, and select internal components, offering flexibility for end users.
