Re: Rings - Aluminum VS Steel
most companies that are making quality rings (badger, seekins, nightforce, EGW, larue etc.) offer rings in both aluminum and steel
some of the larger ring sets , like the SSDS/USMC set weigh darn near a pound just for the rings (steel)
the design of tactical rings are such that whether they are made from steel or aluminum, they do their job well
most have two or sometimes more ring cap screws per SIDE of the ring, and the picatinny rail slots are designed so that the rings have a matching 'rail' on the ring bottom that goes in the slot to mitigate ring/optic movement under recoil
i use aluminum almost exclusively, because i want to save the weight; your big three in a rifle for weight are
barreled action, stock and optics package
any weight saved is good in my opinion ; and my rifls still end up weighing 10.5 -14lbs depending on how they are spec'd -
this is down though from several i owned that were 15-18lbs
you can expect longevity from aluminum - buy a good quality ring from the companies listed and they will stand behind their product;
