I like the fastfire idea but thus far have been too cheap. I did buy a used on on the classifieds here that wasn't worth the price of shipping, but that's on me buying a used electronic sight I guess. I have XS peeps on both my 357 and 44 Marlins, and the XS scout rail with Tasco red dots. Not ideal, but the one has been on a half dozen different rifles over the years, never failed me yet. Worst case, you can use a knife blade to turn the screws and take them off and voila ain't no flies on the XS sights. I checked zero on the 44 yesterday with the dot, was in a 3 inch sticker from 7 yards back to 100. Works for me.
