Last year Strike Industries launched their first red dot polymer cover, made for the Trijicon RMR. They have just launched their second cover, this time for the Eotech MRDS. The cover protects the sight while still allowing access for windage and elevation adjustment and it does not interfere with the ambient light meter. The Strike MRDS Cover costs just $7.95.
Made from hard, yet flexible, Thermoplastic Polyurethane (TPU), the Strike MRDS cover increases the impact resistance of the MRDS. In addition to covering the main body, the cover creates an offset from the MRDS lens. This will help prevent damage to the lens when it is being used as an aid for reloads off of belts, holsters or other surfaces.
Strike Industries told me they are looking to partner with optic makers to manufacture polymer covers for their products. Any companies interested in partnering with them can email email@example.com.
