I have the Chinese SKS that I put a Tapco stock on. I haven't shot it for a couple years and the Grand kids (late teens) wanted to take it to the range. To my surprise I found about a 16th of an inch slop where it locks together. I checked to make sure the latch was fully engaged, and it was. It shot fine and with the kids shooting it I don't know if the accuracy suffered at all. Has anybody experienced anything like this. I suspect it will be a real chore to make it tight again. Any thoughts on this will be appreciated. Thanks.
