The CQTWS Duty Series Pistol is a precision-made, mission-ready pistol engineered for everyday service use with proven performance and lasting durability. Configured as a compact 5.56mm AR pistol with a 7.5" or 10.5” barrel or 300 Blackout with a 8" barrel. It is magazine-fed and cycles via a direct impingement gas operating system. Developed at the request of multiple governments to improve on existing offerings in the marketplace, the Duty Series is built around the CQTWS Proprietary DT (Dissipator Technology) gas block and gas tube, which delivers reliable, consistent cycling and eliminates the failures common in thin, inefficient standard gas systems. Its precision CNC-machined 10.5” MIL-B-11595E 4150 steel barrel is nitrided and hardened to 58 Rockwell with a 1:7 twist, high-pressure tested and precision chambered for maximum accuracy and an extended service life. A full-length, free-float aluminum M-LOK handguard with a continuous 12 o’clock picatinny rail and precision torqued barrel nut keeps optics and accessories rock-solid, while the MIL-SPEC forged 7075-T651 receiver, M16-style 8620 bolt carrier group, and HPT/MPI-tested 9310 bolt provide battle-proven reliability. Vertically integrated and manufactured in-house from high-quality, US-sourced raw materials, every CQTWS Duty Series firearm is built to exact standards and proudly made in the U.S.A.
