Lyman 3121040#12 Slot Blank Tool

Q: What is this length x width x height of this blank?

Length is .650 Width is .444 Height is .130 at the end. The top is slightly rounded like in the picture which gives it a nice appearance. I chose the Lyman over the Marble's because I read the Lyman is finished nicer.

Q: Will this fit the Winchester model 1886 (new rifle)?

If it has a standard 3/8" dovetail slot, it should fit. Some filing might be required, but it is better to be snug than loose (easy to take metal off, but hard to put metal back). I installed one on a Marlin 1894 with no filing; it was tight, and took a heavy brass punch and hammer, but it's in there for good.

Q: Will this work on the rear sight dovetail on a Ruger 10/22?

Yes, it will work, but, generally, most all slot blanks & also replacement rear sights require some fitting, usually in the form of some gentle filing on its bottom surface. Slot blanks should NOT be a slip fit, but should be able to be tapped firmly into place with a brass, or preferably, a hard nylon drift punch (to avoid marring or battering) and a hammer. It is always good practice to remove the action/barrel from the stock and clamp it firmly in a padded vice, before attempting to fit the slot blank.

Q: Just ordered a Skinner winged peep. Will this fit a Marlin 1894? or should I get this from Skinner also?

If it's like the 3/8" dovetail on a marlin 336 rear sight it will fit but needs at least 1/16" ground off to match the barrel profile. Without that it just looks like something you put there that happen to fit the slot. If that makes sense.
