The early 760s with the tube the forearm slides on all the way through are better for using the sling swivel that attaches to the end IMO. You can put some stress on the telescoping type mounting the sling swivel on the end of them. The main difference between the 760 and 7600 is the 760s have multiple bolt locking lugs like a Weatherby and the 7600s have 3 lugs. I don't know what year Remington's quality started slipping but the early 7600s are regarded as better than the new ones. 760 quality seems the same throughout production. I may be wrong but IIRC the carbine barrels are a bit heavier (thicker).
