Re: Leupold mk6 3-18 w/ tmr reticle
wm.penn the Leupold has a lot more adjustment than the LT does. The LT will get a .308 out to 1k with 12 mils, but the MK6 has 100MOA of adjustment, a considerable difference. I'd say that was the biggest reason to go with the Leupold. If you need illumination and will not go over 1k, the LT would be a great option. If you might need more adjustment, and will not need illumination, or need the absolute smallest package, the MK6 is it.
