This great side mount is manufactured by the same factory that makes Vepr rifles. The mount is designed for Vepr, AK, Saiga and other AK-variant rifles with an installed side mounting rail. If your AK does not have an installed rail, you can find a full selection in our 'Side Rails' section. This mount has never been available in the West until now and is very difficult to find even in Russia. Unlike virtually every mount produced for the AK rifle, this special design both centers the rings over the centerline of the weapon and provides the lowest mounting platform available for ideal cheek weld. There is no other mount on the market that we know of which is both centered and ultra low profile! The rings are vertically/horizontally adjustable. Removing pre-installed 5 mm plate (marked by arrow on the mount picture with dimensions) lets you place a rifle scope even lower to the barrel. A scope on this mount sits LOWER than in LOWEST rings installed on MOLOT Vepr/AK/Saiga Extra Low Profile Side Mount with Weaver rail! So your Aimpoint could be even more co-witnessed with the front sight than ever for lower price! The distance between inner surfaces of rings is 58 mm, between outer surfaces is 87 mm. High grade silumin construction to last a lifetime.
