The Meopta R1 is a terrific scope, but Leica ERi has superior resolution and a better illumination system. It's one of the very best bargains out there right now and truly ranks as alpha glass. Mine was a 3-12x50/4-a, and it even outperformed the SB Zenith 2.5-10x56 in terms of low-light performance and was virtually on par with the Kahles CSX 3-12x56 in moonlight.
