Shotgun Front Sight Fix

[Blcksmk]

I have a Norinco Shotgun that I use to mess around with and as a beginning into 3-gun to local indoor matches. The more I have shot it I have noticed the front sight sliding out of the dovetail and it has become extremely loose. I can push the sight left and right with my fingers.

I'm unsure what to do in order to fix this problem since it's so loose. The only idea I have come up with is to dead center the front sight then drill and tap a small hole for a set screw to go into the base of the sight in order to keep it from moving. I put up some pictures below to show how far the sight goes off but won't slide all the way out.

Get a feeler gauge set from Harbor Freight or another cheap tool shop. Make a shim from whatever feeler gauge is appropriate and install the sight with some Loctite 272. Shouldn't come out again.

You could do the set screw, use some loc tite, or just peen the edge down a little. The set screw is the best idea though

If you use loctite this is the one to use. It isn't a thread locker it's a retaining compound for press fit stuff http://www.dawsonprecision.com/ProductDetail.jsp?LISTID=800010BB-1388518283

Thanks for all the input! I'll be fixing it soon and gonna give the set screw a go.

Set screw + above = no problemo
