IMHO the Trij is a decent $1,150.00 optic, nothing more, nothing less. I have one because I wanted to try a 1-8x, they were available, and had received pretty decent reviews. I've not been disappointed, its been pretty much what I expected... I didn't expect it to be up to the measure of my Nightforce. One thing I wish Trij had done a better job with is the illumination, which absolutely, positively does not match up with my definition of daylight-bright (that despite the many claims to the contrary). Again. not disappointing, as that's what I expected after seeing said opinion on M4C from reviewer(s) I trust. If, though, I’d have purchased it expecting true daylight-bright performance I would have been sorely disappointed.
All that being said I'll definitely be giving the NX8 a look. If the illum is truly as bright as initial reviews claim (I've learned, the hard way, that "daylight bright" is highly subjective and very-much in the eye of the beholder) you'll probably be seeing my Trij in the PX.
