Yes it folds forward and back. There is no locking lever just a strong detent that holds the sight upright. The stem and knurled nut are tight to each other and work good together. The knurled nut is on a bushing type thing and it's gotten loose over time and wants to move up and down. I read some where that the first year savage tang sites from lyman were not marked at all so i would like to keep it because I believe it came with the rifle. The one he wants me to trade for is a later sight. Any help with how to tighten it up would be appreciated. Thanks
