What do you like or dislike about them ?
What model and reticle ?
Would you buy another one ?
Is their another brand or model you'd rather have ?
but the price on those is crazy high.
however the battery life SUCKS and the N bats are hard to find. Not sure about other model battery lives but don't get the N cell.
Older M2s or new C3s can be had around the EOTech price range. You can generally find M2s in LaRue mounts in the $400 range on the used market.
The XPS's have about 600 hours of run time on a single CR123.
I think i have seen some as you describe, but I am looking at probably getting a Comp M4 and THOSE are ridiculously expensive.
