The Cobalt Kinetics A5-CK Buffer Kit is a collaborative buffer system developed by Cobalt Kinetics and VLTOR for AR-pattern rifles, designed to enhance recoil mitigation and operational smoothness. This complete kit includes the Cobalt/VLTOR A5-CK H0 buffer weighing 3.80 oz, an A5 buffer tube, and an A5 length spring, providing a comprehensive upgrade over standard carbine buffer systems. The buffer features a raised anti-tilt design specifically engineered to address carrier and buffer cavitation issues in gas impingement systems, resulting in reduced unnecessary movement and improved reliability. Constructed from 7075-T6 aluminum with an anodized finish, this system requires a longer seven-position A5 buffer tube and is not compatible with standard carbine receiver extensions.
The A5-CK buffer system represents an evolution of the VLTOR A5 platform, offering shooters a precision-engineered solution for smoother operation and enhanced reliability. Professional installation by a trained gunsmith or armorer is recommended to ensure proper function and optimal performance.
