Abstract
A countercoil and recoil damper for an automatic firearm which ensures floating support of the weapon during automatic bursts of fire is disclosed. To achieve this, the damper provides annular spring packs (32-35) and a precompressed spring (24), colinear with the other annular spring packs. The precompressed spring is a coil spring which is compressed during countercoil and is released during recoil in order to increase the hysteresis of the annular spring packs (32-35).
