Trijicon Tenmile vs Tenmile HX

Yes, HX=moa while non-HX=mil.

I have the 3-18, as well as a 4-16 AccuPower, 1-8 AccuPower and 1-10 Credo HX. All have great clarity, and precise, repeatable adjustments.

Watch Eurooptic.com for their clearance deals, as well as ExpertVoice if you have a login there. Both often have good pricing.
