1916 Erfurt "Failure to ****"

Remove the upper receiver with toggle from the lower frame. Open the toggle fully and then close the toggle slowly. In the last half to 3/4 inch before the breechblock is fully forward you should actually feel the sear engage the spring loaded firing pin as you close the breech. If you do not, then either your sear is worn beyond use, or has been filed down by some previous owner, or the sear engagement surface on the firing pin has been altered or damaged.

Remove both the sear bar, and the firing pin and take clear focus photos of both from different angles so we can diagnose the problem further.
