I just climbed out of this rabbit hole.
Larue for tube, but Spuhr or ERA TAC unimounts, they also make rings, for their pic rails and height spacers. I think I like the ERA TAC better. Went with 1moa RMR. Will zero at 600 yds. Who knows, it may be a total distraction, but I already find it faster to drop into a high magnification on target.
Very excited for 2021 season.
