The thing gets about 3/4 of the way in and gets jammed, the rails are clear and oiled so I can only assume it is incorrectly sized.
Cover does not fit may be too small. Made in India.
Don't waste your time. This stupid thing won't even fit my Type 38. It's so tight that when I tried to close the bolt with it on it got stuck and I had to hammer the bolt backwards. Find an original instead of getting this piece of crap.
This item is well made, slid right on my rifle easily and functions well. This is a great value.
