Re: Need help Aluminum or steel ??
Far as I can tell the only real difference is weight, and Al is less likely to corrode. Maybe if you had a really heavy scope in really tall rings and really hard recoiling rifle, there might be enough happening to break Al rings, but I doubt it. If you plan to R&R scope or rings allot (monthly or more) steel threads and rail will take that abuse better, same goes for installing or checking tightness regularly without a torque instrument. TPS alledgedly has bad CS, and there have been posts on here about their aluminum rings needing warranty. I have their steel rings, they're very well made, but quite heavy, also the lows are .925, and on a weaver 20MOA rail have enough 1/16" clearance for a 56mm obj on a SPS-V.
