So far my build is as follows:
Aim Surplus Grim Reaper stripped lower
Milspec RifleBuffer and tube
Rock River 2-stage trigger & matched competition lower parts kit
Kies Anti-rotating pins
JP enterprises 3.5lb trigger springs
Kies Oversized take down pins
Magpul BAD lever
Magpul MOE+ grip
Magpul PRS stock
I plan on going with a Nickel-Boron BCG and a 20"-24" barrel, no idea on hand guard, optics, comp or brake or bipod yet.

Looking good! I have a PRS on one of my heavy barrel 5.56 ARs and I love it. My 6.5 upper is an AA 19.5" with round carbon fiber free float tube, the lower I'm using is a Colt 6920 with Geissele trigger, Magpul CTR and MOE, BAD lever and AFG, all in Foliage. I wish I could figure out how to include a photo. I'm computer illiterate. Ha.
I didn't see an upper receiver in your list.
Vltor MUR, FTW!

I have not figured out that end of things yet. Have a baby at home currently and that has tied up some funds for a while.
Welcome. Looks like a great foundation. Are you going to have a custom barrel made?
Ok, I have out off the build long enough and am now coming back to it, I have acquired a AA hard use bolt and a Kies Nickel Boron carrier, I am on a search for a 18" barrel now and am trying to get one. had an interesting conversation with Black Hole Weaponry today about why I shouldn't use a Type II bolt and use a Type I, needless to say I am torn and need to really do some more research on barrel. I am going with a adjustable gas block and a rifle length gas set up, already got a BCM upper on the way. Any barrel tips would be appreciated

The only reason to use "type I" bolts was supply. It no longer has that advantage. Go with the AA(type II) bolt you have.

Lilja is doing another small run of grendel barrels!
Don't waste your time with a 264 BHW bbl.Their 5.56 barrels have shot well for me,but their 264 LBC and 243 lbc barrels were a bad nightmare.I have also had some debate with them and the type 1-2 bolts on the BHW forums...No thanks on the type 1...

This^^^ Get in on a Lilja... they will make my next barrel for sure.
Is there a group buy for the Lilja or just by going to their site?

I just got one from the group buy and it's a work of art.
Here's a link to there website:
http://www.riflebarrels.com/products/ar.htm
Grendel info is at the bottom of the page.
Contour specifications for 6.5 Grendel barrels:
At the time of our 6.5 Grendel barrel introduction (January 2014) we are making these available in four contours. These are the AR740 and AR 24 contours shown above as standards for the 204's and .223's and in addition we are also stocking two mid-length gas system contours; our 17" long contour 304 and 19" long contour 318. To see drawings of these contours click on the designation: AR740, AR24, 304, 319. All 6.5 Grendel barrels are threaded at the muzzle with a 5/8"-24 thread - (although the linked drawings above may show 1/2-28).
The 6.5 Grendel barrels are headspaced using a Maxim Firearms bolt. Headspace may not be correct with our barrel using an Alexander Arms or LBC bolt. Bolts are not included. We suggest contacting Maxim Firearms for an MF bolt at 928-486-2296.
Barrel extensions are an M4 type.

Truthfully I have all 3 of the .135 bolts and they all chamber a round, work with the Go and No/Go gauges in the Lilja barrel fine. The Maxim, AA and LBC bolts are all within spec of .135/.136 and if it is .001 less it will still work, I think there is a .003 tolerance but either of those manufactures have the right bolts. Also the AR-15 has play in the bolt to barrel extension, simple fact so it can cycle ammo as a Semi-auto, if its to tight, it can stick, not like a bolt gun people get all hyped up about. One other quick measurement is the OAL needs confirmed due to recent issues, the bolt needs to be 2.810 (.010 longer) to accommodation the firing pin protrusion due to the bolt face being deeper by .010. Standard AR-15 bolts are 2.800.

I talked to JP Enterprise yesterday, they have plenty of Grendel Barrels in stock. They have barrel (18" & 22") & bolt for $569. There Barrel kits are $759 but includes a timed comp or muzzle device of choice, adjustable gas block and match bolt. I think all you need is an upper, bolt carrier & small parts and HG to finish the upper receiver then drop it on a lower. The comp, bolt, GB and timing the comp is a $350 value added into the price is the way I look at it. I use there LMOS so if you don't have a bolt, they have the Enhanced Bolt Carriers in stock too and the Silent Capture Buffer System to make it all work together smoothly. And since your ourdering, the thermal disipator for the heat reduction and rigidity.
Just another reputable company with Grendels on the shelf.

Your AA bolt will be fine for the lilja barrel. Personally, I would get a second bolt to have on hand just in case you load a little warm. Mark at PF can hook you up or you can call maxim. When you are ready to build, let me know and we can have a build day while the ladies have fun.
