Best scope rail for new Rem 700

Re: Best scope rail for new Rem 700

Just basic comparisons would be:

Aluminum has 2-3 times the thermal expansion
Aluminum has about 1/2 the weight
Aluminum usually has less strength
Aluminum can corrode, steel can rust

Unless they are magnums, either type really should be fine. Be sure to bed it which ever way to ensure a snug fit and be stiffer.
