I'm not much of a shotgun guy, but I think you'd need a low comb stock to shoot a shotgun properly with just a bead, I can use some monte carlo stocks with a WGRS peep sight and they work fine with a scope of course, but even the low comb stocks work for a scope and are preferred by some over a monte carlo. So unless you're gonna have sights or scope on the shotgun, get one of their low comb stocks while the barrel is being fitted, you can look at all the stocks in the "let's see some Handis" link in the FAQs, they're made in pallet wood, walnut, laminated and camo, some straight, some pistol gripped, checkered and uncheckered, lots to choose from.
