I had a KV-04S side mount rail that after 4 or 5 months got too loose and started sliding off the rifle. It's not as though I was constantly mounting and unmounting it, although I did take it off and put it back on some.Zane Zackerly said:It seems like the "small throw lever" type mount would have to be re-adjusted occasionally to compensate for wear.
Horse said:FYI I made a video of this same instructions. Granted - it's for my mount, but the lever used is the same.
It might help some people:
