Yeah, the sights are good and everything (similar/identical to Fabarm sights actually)
I just couldn't gel with them.
I have the same sights on another shotgun and I'm not 100% on those either. But I can tolerate them on that one. The front is fine. It's the rear two dot setup I don't particularly like I guess.
I prefer a bead/pedestal only front sights, or that with a rear ghost ring.
The only differences you can see there between the MPS and the MTS is the MPS has a tactical field style stock, and one of Hatsans pedestal fiber optic front beads.
