My 308 BLR has a Leupold VX-2 3-9x40.
A 3-9x40 just looks to big on these rifles imo.
Respectfully, I don't agree, but maybe I'm biased since that's what I have. Either way having our own opinions is fine. Additionally, to me, looks don't matter much. It's the function that's by far most important to me and the function of the rifle scope combo is great for me. Said differently, even it I agreed with you in that it looks funny I would still almost certainly have the same setup.
Attached is my previously mentioned 308 Win for reference...
