This is the wide duplex, not the heavy duplex. Bought this to put on my 45-70 Henry. Decided to stick with the Skinner peep. Has been mounted once and to the range, but just don't have a rifle this scope is right for, now that the 45-70 is out. I bought this scope at Midway in August, on sale for $244. I will ship to the new owner for $199 (how's that for marketing? ).
