the pre-68-ish 760's had a fixed mag tube that extends beyond the end of the slide handle that had a cap on it that you could replace with an uncle mikes eye-bolt. the carbines and post-68 guns have the telescoping style of mag tube/slide. you can get sling swivel mounts for both. the post-68 style is actually a freefloated barrel while the pre-68's have a mounting bracket on the end of the mag tube that contacts, but does not attach to the barrel.
most 760's are good quality and very accurate. as with any gun though you will get a dud now and then. i have a bunch of them, in both rifle and carbine and all function and shoot excellently, as do my 7600's. the only downside is the trigger on most of them could use some work. i have a 7600 35 whelen carbine that i put a match grade trigger in that is sub-MOA with factory ammo. if you have any specific questions about your gun, shoot me a pm and i will try to help. i've been a remington man since i was a carbine.
