I just bought this weaver style rail for my Baikal (IZH) Mp-61, Because The original 11mm rail on the rifle is short and not too great. Nevertheless, this weaver rail mounts like a glove on top of the original. Since this is a rather compact rifle, the added elevation It provides is a great plus. No more hunching to get your eye aligned with the sights (I put a red dot on it). And should I want to use the original sights, I only need to remove the red-dot, Because it is not so high did it gets in the way of your line of sight.
The quality is just like it Should be. It is a light-weight all metal construction, with three screws: two to mount it and one to keep it from sliding. I shot some 50 pellets with it and it hasnt even moved a millimeter. Further More, the price was good, the delivery quick and what the package fits your mailbox, so there is no need to wait at home. In conclusion I can only recommend this product.
