It went together just right the first time for me , but I used to own have of a sport shop that sold archery and muzzleloaders and am use to working on them [retired 19 years back at the age of 54.
I like to shoot heavy loads hunting and some times you can not pick your position when taking a shot. I really do like the extra eye relief.
There are several good steel rings and bases I never use the aluminium ones I had to change to many of them that stripped the threads under recoil.
I have never had a problem with any of the steel ones so I would say what ever steel one is available will be find.
