I know it has been done so hopefully someone can tell me what size to go get.  I want to change the big screw knob on the LMT sight to a button head cap screw.  What size do I need?

That's #10-32 in fastener-speak Wink

You might try part number 91581A345 from McMaster-Carr (www.mcmaster.com).

Take care,
Clint

Received the following from Yak promptly.  Thanks.

Don't dremel first.

On my first one I backed the knob off as far as I could and then dremeled the shank off. It barely has enough threads to hold the lock nut on. The second one I did I took a set of vise grips and just torqued the knob completely off. Then I put the lock nut next to it to see how much shank I should leave and cut off the excess.

You can get the lock nuts at this link. http://www.mcmaster.com/ and just search for part #91581A345.
