MP-40 Disassembly Return to MP-40

With the bolt forward, and the magazine removed, pull the locking stud (located on the underside of the main body, just behind the magazine well) and give it a half twist to lock it there.

Holding the MP-40 by the magazine well and pistol grip, rotate the two apart and pull the receiver forward.

You can now remove the bolt assembly by pulling the bolt handle straight back.
