Hi all. I just purchased a new sub2k and I'm super pumped to get it. What's the consensus on best red dot mounting strategy for the sub2k? Is it mounted directly on top, which you remove when folding the bad boy? And if so, does it stay zero'd in / sighted when put back on? Is it one of the angled mounts where the red dot is off to the side a bit? Are people happy with this approach? And are there any of these where the gun is able to folded and locked into place? Also is it better if this is mounted on the top rail or on the side with m-lok? Is it one of the hinged mounts supplied by the likes of Midwest Industries or mccarbo? Those are awfully expensive. And do they stay firm when folded in place for usage? Also, what are considered the best red dot / green dots for the money? Any highly rated budget red dots? Thanks!
