SENTRY MANUFACTURING GASLOCK CHARGING HANDLE CQB FOR AR-15/M4 The Sentry Manufacturing GASLOCK CQB Charging Handle is a premium AR-15/M4 charging handle developed in response to OEM demand for a high-performance, duty-grade charging solution that maximizes reliability, ergonomics, and gas mitigation. Incorporating the proven engineering features of the DEADLOCK product line into a traditional charging handle configuration, the GASLOCK CQB delivers enhanced performance while maintaining familiar operation for military, law enforcement, and professional users. Its independent dual-latch architecture allows the charging handle to remain operational even if one wing becomes damaged, ensuring continued functionality in demanding environments. The balanced design also provides smooth, consistent actuation forces for improved manipulation and user control from either side of the firearm. Advanced gas-management technology is achieved through a patent-pending shortened hard-stop gas key channel and full upper-receiver encompassing high-shelf geometry. These features work together to significantly reduce gas blowback to the shooter, enhancing comfort and minimizing distractions during extended shooting sessions. Aggressive texturing on the operating wings and rear contact surfaces ensures a secure, positive grip under adverse conditions. Whether operating with gloves or in wet, muddy, or high-stress environments, users can confidently manipulate the charging handle when it matters most. Structural durability is enhanced through a reinforced angled gusset at the gas key contact interface, delivering approximately 30% greater strength than conventional charging handle designs. This added strength helps reduce the likelihood of failure under hard use while increasing overall service life. Precision-machined from 7075-T6 aircraft-grade aluminum and finished with MIL-SPEC Type III hard-coat anodizing, the GASLOCK CQB provides exceptional resistance to wear, corrosion, and harsh environmental conditions. This robust construction ensures long-term reliability and dependable performance in demanding applications. The assembly is completed with U.S.-manufactured extreme-duty hardware throughout, providing maximum durability and confidence for professional, duty, and operational use.
