My only concern with an aluminum rail is different expansion rates in changing temperatures between steel and aluminum. But I really want somebody else to be a guinea pig for the Seekins unit...
If you are not concerned about a few ounces I would go with the steel :wink:.
I am considering going with the rail on my new 280AI as well. I am at the age now that I really do not have to do a lot of walking so weight is no longer as big a concern :mrgreen:
I use titanium bases from Murphy Precision, I have a brand new Remington 700 LA
25 moa base I'd like to sell w/ 8/40 screws if anyone is interested? Light weight (3.2 oz.) and yet very strong and stability is not an issue!
