Ordering Process
 
1. Select Manufacturer and Model of Gun. (Winchester 1892 Replica made by Uberti, the Manufacturer is Uberti)
2. Select Sight Base Manufacture part number. (This is the base only that will be attached to the tang of the gun)
3. Select the Mounting Screw Set. (Some bases are interchangeable with multiple guns but need specific screw sets- Example: T/C Scout takes the same base as Uberti 1885 but the screws are different)
4. There are 4 interchangeable uprights that are sold separately. Each allow you to adjust elevation out to different ranges with the same base. Our #1 upright (shortest) does not clear the receiver on some guns to the lowest possible upright to purchase for this gun is our #2 upright. (lowest setting will start you at short range shooting out to at least 100 yards)
