Hello Jackknife, there pretty good to be honest, I would opt for the Apex XD75 over the XD38 or XD50 , I have one fitted to my HMR and it is totally lethal, no mucking around with IR torches, massive field of view, instantly on target, its good and the 6x mag helps, even if its digital, it helps a lot with longer range shots, everything looks bigger to me anyway compared to using night vision at similar distances. I was watching two roe through it the other night, and they stood out like a sore thumb 300yds away.
If you want to take a look at mine, you can I'm away till the end of next wee
