No practical experience with that scope, but everything I've heard is that Leupold Mk 4/5 series are top quality, America made scopes. I'm looking at the Mk 4 LR/T 4.5-14x M1 and Mk 5HD 3.6-18x. Nightforce optics are on my short list as well, but they tend to be higher priced and I'm not sure they are any better than the top flight Leupold optics. Military and Police still use both brands. I read recently that the Marines adopted the Leupold Mk 4 MR/T 2.5-8x for their M38 DMR squad rifles.
The Marines and Special Operations are using the Nightforce ATACR M571 5-25x and some variants of Nightforce NXS. Not that it necessarily matters for us civilians, but when the DM's and Snipers in the military are happy with a product, you can generally be sure it is solid. At least that has been my theory in terms of optics.
I currently have a Trijicon 3-9x that has been nothing but solid on an AR-10 platform. Plan on picking up a Trijicon VCOG 1-8x for my HK SL8/G36 build in 5.56. The Leupold/Nightforce would be as a replacement for the Trijicon 3-9x or for a new platform in .300 Win or .50BMG.
FFP is all the rage because it maintains the same size reticle for any magnification, but I find in practice I shoot at the max magnification regardless. My Trijicon is not FFP, but I'm at 9x all the time anway. Might not be the case for a 25x used for hunting where scanning with a lower magnification and range estimate using the reticle on a FFP would be useful and then dialing it up to make the shot, but that seems like a lot of money compared to non-FFP optics for an edge case for me (I'm not hunting with it). YMMV.
As an aside, opticsplanet is offering 9% off everything if you use the code FLASHPOINT, expires tomorrow some time.
