I'm looking at getting another upper for my Grendel, currently I have a 16 inch barrel. What is the best length for long range. I will be reloading so I can get the most out of this round. Point me to the proper place to look if this has been answered before thanks.

Something to consider is the profile of the barrel. A Friend has a 24" AA upper with a Flash Hider and it has a mid weight barrel. The rifle is really not practical to shoot off hand but does rally well shooting prone or off a bench. The rifle is a little long and cumbersome but not nearly as bad as a Friend's 24" bull barrel RRA 5.56/223. My Son in Law has a medium weight Stainless Steel 22" 6.5 Grendel with a recessed crown and no muzzle device. I could shoot this rifle off hand and doesn't seem any more awkward than shooting my 20" Shilen Match barrel with recessed target crown and no muzzle device.
Threading the barrel and adding a Flash Hider or muzzle brake adds to the length and weight. Fluting can help a little with weight but I think the 24" 6.5 Grendel with heavy barrels are only good for static shooting from prone or bench. A medium to light weight 22" barrel could fulfill a lot of task and still provide a little extra velocity. I bought my 20" Shilen and I really like it's size and weight.

Here is a graph that gives an indication of the velocity produced by the different barrel length with the 6.5 Grendel.

I guess 600 yards would be max at least for now and 1800 to 2000 feet above sea level. I want to use it for prairie dogs and pronghorn. Been looking at precision firearms uppers and want the best accuracy I can get. Sorry about being hard to follow just trying to get the most for my money. Would like to use just this round for all my shooting just switch uppers.

A 20" 6.5 Grendel at your elevation will be very capable. I've shot my carbine gas 16" 1:9 twist 6.5 Grendel out to 600 yards and got less than an MOA groups. Using a 20+" 6.5 Grendel at 600 yards is very doable, spend some time comparing the velocities from the different barrels. May help you decide which barrel is best for your goals.

I know a lot of people on this site build their own ARs, I would if time permitted. What are your views on Precesion Firearms company. They have a couple of uppers that I really like and accuracy is very good. If I did build one accuracy would be priority and any help from you all would be appriciated.

I lost track of how many rounds I was putting through the same hole with one using PF 123gr SMK factory load.

I agree with what '52 said.
I had PF build me a complete gun using a Lija barrel. It shoots very well but I have spent more time looking for that special load and I'm still not finished.
The PF upper I bought from a forum member has the same barrel specs but is a Bartlien. This thing shoots everything very well. When you look at the ladder tests it just consistently out shoots the other upper.Knowing everthing isnt as important as knowing where to find it.
