Cobalt Kinetics AR-15 Buffer Features The Cobalt Kinetics AR-15 Buffer is engineered to deliver dependable consistent cycling within the buffer tube of a standard AR-15 pattern rifle. Machined from aluminum it offers a lighter alternative to steel buffers while still providing the mass needed for reliable bolt carrier group movement. The black anodized finish protects the surface from wear and corrosion keeping the buffer functioning smoothly over repeated use. Shooters replacing a damaged or worn factory buffer will find this component drops directly into the existing buffer tube and spring assembly. At 3.8 ounces the buffer sits within a practical weight range for shooters seeking a balanced recoil impulse without excessive bolt bounce. Its anodized aluminum construction keeps the component light while maintaining the durability needed for high round count use. Cobalt Kinetics builds this buffer as a direct fit replacement part making it a simple way to restore or refresh an AR-15 s cycling performance. This buffer is a practical choice for shooters maintaining or upgrading their rifle s internals.
