Piston seal nut for Walther LG55, LG53, LG51. etc. These fit the undamaged factory Piston. Reproduction.
If the factory threads on the piston are damaged, we can cut new threads on your piston and fit a new nut that has the same shape as pictured but with threads to match the piston. If the threads and stud are too bad to be re-threaded to a smaller size, we can machine the piston to accept a screw and provide a screw with a head the same shape as the nut.
