Ok, I have been round and round with Gander Mountain about this... I purchased a 18.5" SuperNova tactical at the start of the summer. The FIRST time I shot it, the rear sights came off. I was in the field, and there was no finding them... I talked to Gander Mountain (where I purchased said shotgun) and they wanted $$$ to replace the sights and they had only stock to choose from. I went to officerstore dot com and bought some meprolight tritium sights for a reasonable price. However, they don't fit, even though the website said they were for my model. So now what, besides send them back...does anyone know of another site or store that has reliable info on night sights for this model? Thanks.
