I owned a 760 in the past and loved it, so I just picked up another yesterday. The question I have is this: My previous gun had a "stud" on the end of the forend to mount the sling from. My current gun does not have this and a clamp is mounted to the barrel for the purpose of the sling. Can anybody tell me the difference between the two guns? Which one is older, more desirable, anything particular i should check over? I value and respect the knowledge of our members and would appreciate any info! Thanks in advance.
