vizslazeus Posted April 6, 2017 Report Share Posted April 6, 2017 How do you remove the rear sight assembly from a mp40 piece? Thanks for any assistance Link to comment Share on other sites More sharing options...
Rich.Urich Posted April 6, 2017 Report Share Posted April 6, 2017 You don't.I have seen them usually stamped into place with two rivet like protrusions on base...I have also seen them brazed into place.Also, inside the base of the rear sight assembly is a flat spring that gets in the way when trying to remove the 100/200 meter rear sight flip leaf.

Rich.Urich Posted April 8, 2017 Report Share Posted April 8, 2017 With the bolt placed in the receiver (or better yet a 1 3/8" (??) metal rod (I have used drill rod) to prevent crushing the receiver tube when placed in a soft plastic vice jig I had made to place around the receiver section while in vice. The best way would be to make a tool to slowly push out the sight leaf assembly (sort of like a screw-like front sight adjustment tool)This tool needs to grasp the base of the rear sight while pushing out the leaf sight... and with a dental type pick or tweezers, remove the flat spring when the sight leaf assembly is pushed out of the way far enough. Reverse process with the dental pick or similar device pushing down on the leaf spring while pushing back the sight leaf assembly to the original marking spot. The less desirable way to do this... (because you run the risk of damaging the surfaces and finish of the rear sight parts) is to gently tap out the sight leaf assembly with a plastic/delron/hard wood "punch" just far enough to use the above mentioned tweezers/dental pick to remove the "bad" spring and replace with new one; and then use the above mentioned reverse process. Ideally, find a Class2/3 dealer/gunsmith who has done this repair successfully in the past and pay them to do it right. Link to comment Share on other sites More sharing options...
Junkhunter Posted April 8, 2017 Report Share Posted April 8, 2017 Yeah...... I will find a guy. First thing that happened when I got my mp40 flipped the leaf up and broke the spring. Link to comment Share on other sites More sharing options...
Rich.Urich Posted April 8, 2017 Report Share Posted April 8, 2017 Springs go bad...Firing pins and extractors break...Age and wear gets all of us. Link to comment Share on other sites More sharing options...
TSMGguy Posted April 20, 2017 Report Share Posted April 20, 2017 70+ years after the fact we're seeing demonstrations of how cheaply produced these weapons were. They were not really meant to be serviced, just replaced when they wore out or became unservicable. Link to comment Share on other sites More sharing options...
geefal Posted May 11, 2017 Report Share Posted May 11, 2017 70+ years after the fact we're seeing demonstrations of how cheaply produced these weapons were. They were not really meant to be serviced, just replaced when they wore out or became unservicable. Very poor information here. They were in no way meant to be simply replaced. Specifically in weapons manual D167/1 a listing of parts and repair interchangeability is specified for use by unit Waffenmeisters in the rebuilding and repairing of damaged weapons. Do you really think they are going to throw a complete gun away because of something as simple as a broken part. Really..... Link to comment Share on other sites More sharing options...
