Abstract
In some embodiments, a firearm mechanism comprises a bolt carrier comprising a bolt carrier cavity, a buffer comprising a buffer cavity and a weight arranged to travel between the bolt carrier cavity and the buffer cavity. The buffer cavity comprises a damping mechanism comprising a reduction in a cross-sectional size of the buffer cavity. In some embodiments, the damping mechanism and weight comprise a valve arrangement arranged to pressurize the buffer cavity and damp kinetic energy carried by the weight.
