Abstract
A spring damper device comprising a directional spring (e.g., coil) having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).
