Default 6.5 Grendel questions?????

I just finished my carbine build this afternoon and now I really want to put a little more distance down range. I'm leaning twords a 6.5 built but just need a few facts before I proceed. Can I use a standard BCG with a 6.5 bolt or is it a different Carrier completely? Also does anyone know where I can get a 20" or 24" flutted barrel? So help my ignorance. Thanks......

The bolt, barrel, and magazines are different. That's all.

As for a longer fluted barrel, go custom. The wait times aren't that much longer any more (since AA and CSS both have long lead times), and the results are much better.

I was just looking over the Alexander Arms site and got the jist of everything. Going to call around and check on wait times. I'm just worried about buying good glass. Luckily my wife didn't kill me on my last built. Thanks for your input.

There's one interesting/annoying detail to be aware of if you go custom. The 6.5 Grendel cartridge dimensions are based off the 7.62x39 (at least back at the bolt end of things). But because of something AA did, you can't just use any 7.62x39 bolt with a 6.5 Grendel barrel.

Basically, the issue is that AA originally made his own bolts from 5.56 bolts, and when he milled them down, he took about .012 from the whole bolt face. Measured from the barrel extension, AA chambers are .012 shorter than needed to make up for the shift in the bolt face. CSS/Lothar do not do this. When you get a custom barrel made, you can either go with AA or you can go with CSS/Lothar. If you go with AA, you have to use AA bolts. If you go with CSS/Lothar and have your chamber milled .012 deeper, you can use any 7.62x39 bolt (available from M1A and others).

So when you order your custom barrel, let the barrel maker know how to ream your chamber (you may also want to provide the bolt you've chosen to help with confirming headspacing).

Not to thread jack but can you speak more about CSS? Who is CSS? So a 7.62 x 39 bolt is all that is needed? Thanks.

CSS is "Competition Shooting Sports" (http://www.competitionshooting.com/catalogue/category33).

They also sell 6.5 Grendel components, including bolt+barrel kits. I tried to buy one of their kits before the Obama craze hit, but I bailed when I couldn't get email responses. Turned out to be a family tragedy and not his fault, and others have been extremely happy with the quality of the kits (the barrels are made from Lothar Walther blanks).

The AA barrel & bolt kits are made from ER Shaw blanks, so the CSS/Lothar barrels are higher quality/more consistent/etc.

If you're having a barrel custom made from a 6.5mm barrel blank, the only other components you need are a 7.62x39 AR bolt and 6.5 Grendel magazines. If you buy a kit from AA or CSS, you'll get a matched barrel and bolt, and you'll just need to buy the magazines.

yes.
The body is wider inside the mag tube to fit the larger case body diameter and still double stack.

If that upper includes the BCG, then I would recommend anyone even considering a carbine length system (unfortunately, the OP specified a 20-24" barrel) to jump on that deal. It's a very good price for a nice piece of kit.
