It is a Russian Izhmash CM-2 .22lr "match" rifle. Anybody ever seen one? I searched the Web and came up with very little info. I guess it is rather crude in appearance, but is a decent shooter for the money. I need a target rifle for 50 and 100 yard prone matches. Its sights are said to be superior to the  Redfield and Lyman peeps. I might save for a Anschutz of some kind, but this rifle is intriguing.
