T651 is said to have less residual stress from the tempering process , it's prestressed during tempering and is supposedly less stressed and moves less when machining .
I've never seen a difference
Personally I would not use 6061 for a tensioning sleeve as it's very soft and pretty week and will compress over time 7075 T6 (or T651) is a much better choice. And if it's for your personal weapon pay extra and get 7068 , it's WAY harder and stronger than 6061 probably 4-5 times
7075 is some tough stuff. Machines noticeably different than 6061. 7068 is a new one on me and I'm a metal/materials junkie. I'll have to look into it.

I work for a NASA contractor as a machinist and get to play with some pretty cool stuff like the 2024 lithium/aluminum alloy they made the fuel tanks for the shuttle with , we used some 7068 and alot of 7075 thats where I was introduced to 7068. So I started shopping around and found that McMaster Carr has is , but if you shop around you can find it cheaper. They never used and round stock at work so I couldent scavange their scraps :-( but it's great stuff , I recently made a form-1 suppressor for my 22 out if it

I think stainless with .050-.075" wall would be good not real heavy.
When I get home this weekend let me look , I may have some 1" OD .065" wall 321 Stainless steel in the shed. What size were you looking to use ?
I was going to do an intrigule suppressor with it (and i had had got a bunch extra to play with making hydrogen generator for my truck)
Hey, I didn't think about that. Would it make a difference on using the heavy wall thickness? Since I'm looking at using the 1/8" wall will that put 6061 T6 back in the running?
