Abstract
A shock attenuation system configured to reduce shock experienced by an optical device coupled to a weapon includes an inner rail support configured to couple to the weapon and at least two outer rail supports substantially parallel to the inner rail support. The at least two outer rail supports are configured to couple to the optical device. The shock attenuation system also includes a first spring feature coupled to a first of the at least two outer rail supports and the inner rail support, and a second spring feature coupled to a second of the at least two outer rail supports and the inner rail support. The shock attenuation system further includes a viscoelastic material coupled to at least one of: the inner rail support, the first outer rail support, the second outer rail support, the first spring feature, or the second spring feature.
