Especially for a local that walks in...no sales tax right ?
Shipping would be $60 or so

Remington got off to a bad start first few years
This GB link is for a pre safety model....cross bolt safety started in 1983 ish which bring decent $$

Had 'em in 444...45-70...450...even had a 'GS' 18" 45-70 stainless.....
Few yrs back had a very weak moment & sold it to my SIL.....):
