Hey THR,
I had another thread going here:
http://www.thehighroad.org/showthread.php?t=803118
But it devolved into a debate about weather or not .308 was a good long range cartridge. So I'm starting a new thread...
Anyway, I am working on building an AR-15 in 6.5 Grendel, specially for shooting at longer distances (500 yards +). So far I have an upper and a scope. Not sure where to go from here, and would value your opinions / advice.
This is the upper I've got:
http://shop.redxarms.com/20-RXA15-65-GRENDEL-TACTICAL-FLUTED-SS-UPPER-2065GRENDELUH.htm
Here is the scope:

So next step is to get a lower and a scope mount.
I was thinking the basic weaver scope mount would work, I don't think I need a 20MOA mount because I don't think this cartridge is capable of shooting far enough to need one anyway. If I'm wrong please let me know.

As for the lower, I think the lower itself is a non-issue, from my limited experience lowers are all pretty much the same, just have a different logo on the side.
I know that the trigger will be important, I see alot of "drop in" triggers for about $200+ and the regular "mil spec" trigger for WAY cheaper. Is there no middle ground on these?
Not sure about the stock either. This thing looked kinda cool:

Like a Magpul PRS but without the pricetag. I know most the time you "get what you pay for" though so I'm wondering if this stock will hold up? Anybody here ever tried one?
I've also thought about getting a cheaper stock for now and just upgrading later (or just keeping the basic stock if it turns out to be OK for me). Something like this maybe:

This upper has quad-rail (not a huge fan, lots of sharp edges). The only thing I think I'm going to attach to it is a bipod. I see they make rail adapters for a sling mount bipod. Is there any such thing as a bipod that just mounts directly to the rail without needing an adapter?
The one thing I'm really not sure about though is the muzzle device. I'd like something to limit muzzle climb. Ideally I think it would be cool to be able to watch my bullet impact. I'm not worried about the recoil so much as the jump if that makes sense.
I don't know if this is even possible though. I have zero experience with breaks or compensators. I also want to be courteous to anybody who might be standing nearby, and I'm told that brakes can cause alot of concussion. Is there any such thing as a break that vents upward instead of sideways? My other challenge is that the treading on the muzzle is an oddball, it's 9/16-24, I don't think this is a common thread for most muzzle devices. Do you guys have any suggestions? Or should I just forget about it and put a thread protector on there?
Sorry this is a pretty vague / open ended set of questions. I'd appreciate your input though. Thanks in advance.
