That is a point of much debate. I like to keep things simple by saying this : SIGHTRON is like buying NIGHTFORCE at a 40% discount. True, we do not have Zero stop, or the reticle choices that NF offers, but the reality is, that stuff costs money.
If I had to have zero stop (i don't) or one of the more esoteric reticles (I don't) Then Nightforce or Kahles is your optic.
But if you Value optical clarity and resolution, Rock Solid tracking and adjustments with no extraneous frilly bits, and Durability without breaking the bank... Sightron is your game
One of my Sightron's I bought from Jerry in 2003 or 2004? 8-32x56, and it has been hunted with, used under a 300 win mag, 30-06, .270, and done some target work... Still Passes the box test, glass is still great.
doesn't matter if it's -30 or +45, this scope has served me well. No issues, never been back for any kind of service or warranty.
My gripe list is pithy and small. Lens dust caps are shyte. I have seen better fitting toppers on last act strippers. Paint used on numbers and graduations is pretty ugly. White would be nicer. Side focus is a little more than properly stiff.
That's it really
