I love it - if you are military Vortex offers 40% off via Expert Voice too - so that makes it one hell of a deal. Something to be aware of however, if you are a fan of scope caps - Tenebraex (my go-to brand) doesn't have an objective cover that fits this particular model. I contacted them to see if other Vortex 56mm objective covers would fit, however they indicated that Vortex has a different thread pattern on this particular scope - so I am running Vortex branded objective cover in the front (eh okay) and a Tenebraex UAC019-FCR for the eyepiece. I am a little OCD about this stuff - so it is annoying - but not bad.
My set-up is the MPA CZ 457 30 MOA Scope Rail. I know that most everyone with 457's are running Area 419 rails, however I find the MPA version to be a bit shorter and cleaner looking (doesn't have the giant "419" on the side). While the Area 419 version does have the built in level - I can't imagine that being very visible once you are behind the scope without moving your head. I am using an Accuracy 1st Level - much better IMO. Reference rings, I am using the Seekins 34mm 1" High. Initially I thought they might be too high, but as you can see from the photo, it leaves JUST the right amount of room for the scope cap.
The last note I will mention - for a 34mm tube - it is not that heavy. But it is heavier than what most are running on their 457s. For me, it is worth it - but I was definitely surprised at the difference in weight once I removed it...haha.
