Have a 20 ga. Topper Model 48 and need to know if it is chambered to shoot 3 inch shells or not. How can I tell? Is there a simple way to measure the chamber or were these guns never chambered for 3 inch?
That's not true, they don't have any information about H&R firearms made before 1987, the M48 was made by Harrington & Richardson Inc which went out of business in 1986.Walley said:Call Harrington & Richardson customer support at (866) 776-9292 and they will be glad to help. If you gun has a serial number they will have no trouble telling you everything you need to know about it.
