Don’t have one, but the Tract 4-12 AO looks pretty good. Like all 1” ones though, it’s lacking in adjustment range, which can have you holding over if you go long.
I have one of your little Burris 6s on my 457. It fits neatly behind the rear sight. My 10/22 CSC has a SWFA MOA 6x. I really like the fine dot in the center of that one, and the numbers next to the bottom lines let me hold without counting. Tracking has been spot on.
