I have ran a lot of ammo throughe my MISR 90 and I have yet to have a problem accuracy? I have and will continue to hunt (close range) with it I did add a one piece synthetic stock ,because with the orginal one peace wood stock I was not able to reach the trigger with my finger.
Ther eis r=trigger slap and the riffle is sloppy but it works every time I ask it too.
Pros:
I purchased it 10 years ago for $200.I put a synthetic one peice stock on it an it has been rock'n&roll'n ever since without a problem....reliable workhorse
Cons:
It is a AK not a fine crafted tool or work of art.
