The Keymod system, a standardized method to attach accessories to rifle fore-ends without the need for picatinny rails, was first unveiled at last year’s SHOT Show and later open sourced by VLTOR allowing any manufacture to make KeyMod accessories. Strike Industries has developed what might be the first Keymod fore-end/rail for the AK platform. One of the main advantages of the KeyMod system is that is allows very slim rails, as you can see in the above photo.
