Just a note for everyone, H&R has said they're switching to their proprietary sights, so don't be surprised if you don't get Williams sights, it's hard telling what's out there, mine has their old style sights on it.
If anyone want both, order the barrel with sights and have them add the scope rail and extension, lots cheaper than doing it the other way round, they'll add $47 for sights on a scoped barrel, but only $18 for a rail & ext on an iron sighted barrel.
