 The high line of sight is a design feature that the Margolin's designs had in common with the famous AK-47.The AK-47, designed between 1946 and 1948, like the Margolin, had high sights which lowered the barrel, put it more in line with the shoulder, reducing muzzle climb.The barrel, being comparatively light-weight, can be equipped with an under barrel weight for added steadiness.
