Ripp,
Just got one of the Remington 798s from CDNN in .458 Win mag. It has a flipdown rear sight that doesn't look to bad. The front is hooded. I will take a picture and post it to see what you think. It does not have a barrel band, just a post on the forestock. It will have to go to the gunsmith for a once over, but for the price, you can't beat it. A friend of mine bought one in .375 H&H.
