Need a little sight assistance....

[DasVidaniya]

I have a Mossy 500 that I am working on, and I decided to replace the front brass bead sight with something I could see.

 

Decided on a Meprolight Tru-Dot ML-34044.  It is a screw in replacement.

Well, it screws in fine but doesn't get tight until the glowing side is facing away.

Do I put in a spacer?  A washer?

Use a pair of pliers to force it around to line up?

 

Help me out please.

You can try very lightly filing  the bottom surface of the site to get it to line up properly. Go very lightly, just a stroke or two at a time. A little goes a long way.

I used a small lead shot placed under the screw.

It depends on how far you need to go, If your only about a quarter turn away, yeah I would put more turn on it with blue lock tight. If its tightening to a max amount just shy of zero-ed out, take a deburing tool and finger spin off a tad amount of metal off the top of the hole. "If" your too far off to do any of that and the sight is relatively firm in the treads, just use red lock tight on it at its zero point and let dry for a couple days, trim off the bore tendon and call it done.
