I put one on an Izvesk 41 SVT40 that uniquely has a serial number in the year I was born 1980 ! Love it
I found this scope easy to sight in at 100 yards for 2-3 inch groups so far MFS FMJ
I do not have a sniper notch only rails and this mount slide on fine and has held zero well for about 120 rds so far.
Only problem I have is that take down requires this bracket to be removed for full cleaning. I have yet to take it all down since zeroing with the pain of having to rezero after. This makes the rifle a factory ammo machine cleaned with a boresnake. I have avoided firing surplus through this rifle for this reason alone. Once I do get to a full takedown I will have a better idea how close the scope will hold when removed and put back on.
also for $400 I expected a cover and caps like when the scope is ordered alone, being a combo item should be included. but the world is no fair. lol tasked my mother to make one with her industrial sewing machines, will pic the result if it happens.
