at $4300 bucks not much of a market at all IMHO...you pay $500 extra for the H59 reticle and even at $3800 for one with an MOAR type reticle they are still pretty pricy for a front focal plane scope...especially since vortex came out with the gen2...with that said i have a ATACR 2nd FP scope i bought 8yrs ago and it has been through hell and back and still tracks as true as the day i opened the box.
a buddy of mine just got an ATACR F-1 but i havent had a chance to look through it...i just bought a vortex gen2 and its an awesome scope so far...it would of been an F-1 if night force would update their reticles.
