Leupolds LRF performance has been historically disappointing, you’re lucky if they range reflective targets to half of their stated distances in ideal conditions.
Not saying they couldn’t turn this around and these could be better, but I wouldn’t spend my money on them until it’s well confirmed.
I would also confirm that they’re made in Japan like the standard BX4 because I’ve heard mentions otherwise. If they’re chinesium you might as well go vortex and have an excellent LRF and lifetime warranty on it.
