BudsGunShop.com - Folding rear sight blade?

Hi Gary and welcome to the Community. The rear sight does not fold down. You would need a minimum of Medium Height Scope Mount/Rings to properly clear the rear sight. Cheers and stay safe! amazon.com/M1SURPLUS-Scope-Mounts-Scopes-Tubes/dp/B06Y1JZPRZ

Gary, unfortunately no, the rear sight doesn't fold. Can remove and replace the sights pretty easy but it's not foldable so if you plan on adding a scope just make sure your rings are high enough to clear or can completely remove the rear sight pretty easy. Sorry but hope this helps.

Gary, this has a Fully Adj. Semi-Buckhorn w/ Diamond Insert rear sight, but it does not fold down. Brass bead front sight.
Stay safe & have a great day!
