I have a set that came off my MKV 240 Bee. Will these fit a vanguard?

No, Weatherby Vanguard/Howa 1500 use the same bases as a Remington 700.

Buy the Talley bases and rings. They are about 110.00 bucks, well worth it.

Or Talley Lightweights. Cheap and strong and light.

Or go S&K and get something that look decent and don't snag on schit.

Two piece, yes. For a one piece mount the spacing is different, so you have to get one that's made for the Howa 1500.

According to Talley, 1500/700 have a different front/rear height difference than the Vanguard, so they sell different mounts for them.

Thanks fellas
