especially the original pattern receiver sight that resembled looking over a nose-high stack of 55-gallon drums, I have found the answer - the Tech Sight RR 200. It's $65, well-made, easy to install, and gives a sight picture almost identical to the Garand and M-14 (the best receiver aperture sights in existence, for my money). After cussing the original rear sight for almost 5 years and trying several alternatives with poor results, I put a RR 200 on my Mini last week and tried it out yesterday. Took a whole six rounds to zero the thing, after which I happily dinged everything within a reasonable distance. I currently have a 2.5X scope in a quick detach mount on that rifle, but I'm not sure I couldn't hit just as well now with the irons.
