Aimpoint CS: Revolutionary Battery Life for the Swedish Home Guard

The Aimpoint CS is an optic designed specifically for the Swedish Home Guard, which wanted a red dot that was extremely durable and also capable of being left on for 10 years on a single battery. This was a very challenging requirement, and Aimpoint considered two paths to meet it. One was a pulsed LED to reduce actual “on” time of the dot, but this did not prove successful. The other was a traditional red dot, with improved design and power circuitry to allow an extended battery life. The new system was integrated into Aimpoint’s other optics (including the US M68CCO contract).

Along with the improved electronics, the CS used a large (approximately AA size) 3.7V battery hard-wired into the case. Per Swedish request, the battery was not user serviceable, and the optics are returned to Aimpoint for battery replacement every 10 years (they are on their third such cycle now). It also includes a set of hard rubber backup sights on top and a small length of picatinny rail that was never really used (it was intended for accessories like laser modules).

The Aimpoint CS was developed in 2001, adopted in 2002, and deliveries of about 60,000 total began in 2003. It was used on Home Guard AK4 rifles, and also on AK5s. They were not sold on the commercial market, and are very scarce in the US.
