Objective: Trade various rail mounts designs to meet the AWST desired capabilities. Companies: DRS-RSTA LaRue Tactical (Austin, TX) Atlantic Research Marketing Systems Inc. (A.R.M.S) American Defense Manufacturing Alamo Four Star Global Defense Initiative (GDI) Engineering Requirements: 3.1.1.1. Weapon Rail Interface. The IWS shall interface to the MIL-STD-1913 rail for the weapons listed above (T). The IWS shall interface to the STANAG 4694 rail (O). 3.1.1.17. Weapon/IWS accuracy. The IWS, when installed or removed from the host weapon, shall not degrade the inherent accuracy of the host weapon system. The IWS shall not be significantly affected by the operational characteristics of the host weapon. Momentary upsets due to firing or shading due to barrel heating are not considered significant. In automatic gain control, barrel heating shall not affect the automatic gain value applied in the critical area of the display. Background
