Can any of you advise the rear sight blade heights for L-frame adjustable rear sights? I need to find the tallest one, along with required hardware. Looked at Numrich, but they didn't list the heights.

Wayne, I have a Word document that lists the sight blade heights for most S&W models. Send me a PM with your email and I can email it to you.

Just so you know it also depends on the barrel length. In this case size does matter - lol.

The tallest rear blade is the .196" blade. AFAIK it only come in black, no white outline.

That's what my 5" bbl. 686-6 uses.

You can buy the whole assembly at Midway:
Smith & Wesson Rear Sight Assembly .196 Black K L N-Frame

.

It doesn't come with the front mounting screw so if you need one:
Smith & Wesson Rear Sight Leaf Screw New-Style Leafs (With Round

.
