Product Description

•••••

Description: Marble's 3/8" Dovetail Sight Slot Blank #87, Blued. Constructed from quality steel and coated in a matte blued finish, this 3/8" dovetail sight slot blank (#87) is perfect for protecting your dovetail slot and is compatible with a variety of rifles produced by popular brands such as Winchester, Marlin, Remington, Savage and more. Please note, this piece may require fitting.

Calculating Rear & Front Sight Height Combination:

1. Measure the diameter of the barrel at the point of the rear sight is going to be installed and at the point of the front sight going to be installed (example: 1.0" rear sight and .750" front sight).
2. Divide the diameters by 2 (example: 1.0" / 2 = .500" and .750" / 2 = .375").
3. Check the rear sight height adjustment chart. You want to be about 1/3 up from bottom adjustment. using a sporting rear #67 adjusts from .300" to .510". Total adjustments is .210". Divide .210" / 3 = .070". Add the .070" to the lowest adjustment height (which is .300") and you come up with .370". This is 1/3 up from bottom adjustment.
4. Add the 1/3 adjustment to the center line distance (example: .370" + .500" = .870").
5. Subtract the front sight center line figure from the rear sight height (example: .370" + .500" = .870").
6. You need a combination of front ramp and front sight with the height of .495". Ramps are measured from the base to the bottom of the dovetails. Front sights are measured from the bottom of the dovetail to the top of the bead.
7. Or you could go with a front sight height of .588". .495" (height need from top of barrel to top of sight) + .093" (which is the depth of the dovetail cut in barrel).

Bought this for my winchester 94. It took a lot of strikes with a brass punch to install and now has a small dent in the side. Probably should have gone over the bottom edges with a file beforehand. I just didnt want to take too much metal off.

Had to do some file work to get it to fit. It looks ok after that.

Did not fit. Not even close. I was a tool and die maker for years. I do my own triggers etc. with excellent results. Smith 41, smith 586 and so on. So when I say it was not close, well, it isn’t! Not much money but still disappointed.
TIGHT!

Purchased for Golden Boy H004 after removing factory sight to install Weaver style scope mount. Fits perfect into Dove Tail opening. It is not a smooth fill but could be milled and blued if smooth fill is desired.
