Help with Scope mount options please

[am4966]

Hey guy's!
I'm new to the forum but have been lingering for the past few months getting anxious for my first ever AR build and its going to be a Grendel!

I have extensive experience shooting and hunting/ building bolt guns but none with AR's.

My question: What type of scope mounting system should I consider on my new Grendel build? Why?

I'll be using a Leupold Mark 4 or VX-3 in a 4.5-14x50mm. The gun will be a 22" flat top. I want to maximize the scope's adjustments for 600-800 yard shots. I don't want or need quick disconnect options. Once it's mounted it's staying mounted.

I should also mention that I'm 6'6 with long arms and will be using an extended stock and grip to suit my shooting needs so proper eye relief is important.

I'm considering the Leupold Mark 2 or mounts but I'd like to keep the scope as low as possible.

Would it be best to just mount with standard picatinny rings or go with a raised system?

Thanks for the advise and input!

I'm 6'6" too and I'd have no probably going with anyone that Vascar mentioned and I have used LaRue before. So it depends on you and what your wallet says. Lol I do agree with Klem once you're shooting 800 yards your gonna want to go farther so get a 20moa cantilever. I'm going to be in a market for b my Grendel 12.5" soon and I'm going worth weight so it'll be Aero Precision, but if it was for a long-range platform. I'd have to really look hard at Bobro, Nightforce or Aadmount. I'd really love a spur but they need to come down in price, by 200.00
