I'm looking at a new scope for the new omark I'm building and am tossing up between a Sightron 10-50 , a Leupold 8.5-25 or a Hakko pinpoint 10-50 I've shot an f-class rifle with the leupold and it was very good, I have a Hakko 8-34 tactical on my f-class rifle which has great optics, but is only 1/4 click and I had an issue with the knobs (they use 4 grub screws to hold them on and I stripped the threads, completely my fault). The sightron I have no experience with. All 3 are similar in price with the hakko being the cheapest but limited to a german retical with a cross hair (similar to a fine duplex without the top post) Any suggestions which way to go and any experience with the sightron?
