I've never owned a M6/760/7600 but the same could not be said for the M14 or M141. When I was young - probably late teens - I recall considering purchasing a M760. My uncle strongly advised against saying, "they rattle like a tin can." For the deep woods hunting we did where the range could be real close, he believed the deer could easily hear the forearm rattle. I have handled many of them and it doesn't seem to take much of a shake to hear the forearm rattle. I've had plenty of experience that has proven to me how well those big-eared whitetails can hear.
