jaspar4 Posted March 13 Report Share Posted March 13 Hello , basically the title says it all ... what are these dents on the tubes of some mp40s? What was their purpose? To be more specific , below are two images, one shows a mp40 without a dent on the tube and the other a mp40 with dents on the tube. Thanks in advance!

RoscoeTurner Posted March 13 Report Share Posted March 13 Not a dent, these are pressed in to hold the trunnion in place. 1 Link to comment Share on other sites More sharing options...

tommyboy Posted March 13 Report Share Posted March 13 Originally they were brazed but later guns were crimped to speed up production. 1 Link to comment Share on other sites More sharing options...

TSMGguy Posted March 14 Report Share Posted March 14 At about the same time the barrel nut with two wrench flats instead of six was introduced, as in the lower photo above. Again, this was done to simplify production. Link to comment Share on other sites More sharing options...
