[QUOTE="Pdvdh, post: 775446, member: 4191"] Keep an open mind when you ask this question, and don't forget that the rifle receiver is made of steel. Lots of suppliers manufacture 1-piece aluminum bases and they get mounted on the steel receivers by lots of shooters, including myself. No problems. Also, remember that the scope tubes are aluminum and many shooters mount their aluminum scope tubes in steel scope rings. And taking it one thought further, the scope tube is almost always aluminum and the rifle receiver is almost always steel, and the different thermal coefficients of expansion doesn't result in damage to the scope tubes. So the differences in the thermal coefficients of expansion is a non-issue with respect to scopes, scope rings, scope rails, and receivers in the temperature extremes we experience in normal use on planet earth. I couldn't say why Leupold recommends against mounting their steel rings in an aluminum base. If their rings are the type that insert into a hole in the base and then have to be twisted 90 degrees in order to lock into place, then I could understand some concern from the perspective of the steel/aluminum bearing friction fit. If they're picatinny style rings/bases, then I believe there would be no problems whatsoever. I suppose you'd have to ask Leupold why they advise against this. It could be as simple as by making this statement, it increases the odds you'll buy some Leupold bases to match your Leupold rings. More profit for Leupold. PS: I'm one of them engineers too. And I admit it even scars me at times! [/QUOTE]
