No, there's a kind of thumb stud you use to flip it up.

There's a reason the seller provided no photos of the front end of the rifle. The barrel was held in the stock originally by the Teutonic sort of key that goes through two escutcheons, the kind of thing you find on old black powder guns. The key and escutcheons are gone, and the escutchion holes are filled with solder. The trigger guard is held on by wood screws. And the front sight is missing. Fortunately, it was very cheap.
