well, what makes it more confusing is that there are Weaver™ brand weaver bases and dozens of other brand weaver bases like Leupold, Warne, Burris, etc.
IMO if you look for ones with the centre channel milled out like the Weaver™ bases you should be OK since the centre is very low profile.
i prefer the flat-topped steel Warne weaver bases when i can get them, but i have to admit that this is merely a matter of personal preference since ive never actually had the aluminum Weaver brand weaver bases actually fail me in any situation. also, they are dirt cheap - at around $5 for most rifles, so theyre not exactly expensive to replace.
the Warnes and Leupolds are usually $30+
