A while back Swatz posted some pics of his gun with a front sight he glued on. (back a few pages) I found the same Hi-vis sight at walmart for $4.00. Am looking for any info on what glue or epoxy would work best for gluing the sight on. Already tried crazy glue...didn't hold. Swatz posted that he used Permatex ultra black hi-temp RTV silicone gasket maker. Any suggestions about what works and what doesn't.
