mine: 6.8 16"

Keep that 6.8 and get a 6.5 Grendel upper from Alexander Arms and use it on the same lower. AR-10 is just way too much money right now.

Use the 6.8 for up to 200 yards or so and the 6.5 for much further....more of the range of a .308 if not further.

I own a 6.8 ar and a fal and the fal get more of a workout just because of ammo prices and I reload. But for hunting go 6.8.

Did you just do it with a dremel?

I did this to a buddy's upper. He ordered and M4 feed ramp upper when the barrel he had did not have he cuts, so we had to. I used one of those stone looking grinding attachments. It turned out great. Looked good and shot good.

I went to randall at ar15barrels.com and had him do it. It only took him ten minutes. he does very good work. It shoots great.

just to give you a heads up silver state armory is coming out with a plinking round for the 6.8 so you can have some fun with it. It comes out late next month. and the price will be reasonable so you can stock up on it as well. check out their webpage:thumbsup:

Why get/keep the 6.8 period when 6.5 Grendel outperforms 6.8 SPC at all ranges? This is what I just dont get. More power, velocity, Higher BC even in hunting bullets, etc. The list goes on. Why even waste time with a 6.8SPC? The only thing that I see is an advantage to the 6.8 (if its even true) is its ability to feed better than the 6.5G.

Oh and get a .308 . You wont be disappointed

F the 6.8. the 308 is the only ammo you'll be able to get.

6.5 might not be the best round for hunting I would think it would have the likelyhood to possibly do damage to meat and I think he wants to eat what he kills. Most people hunt within a couple of hundred yards.

6.8 is more of a standard as more manufacturers have slated to go this route. I wouldn't want to count on a one or a couple of companies to count on promoting the round as opposed to a lot more companies with the 6.8.

6.5 ammo is more expensive when ordering non wolf ammo, which a lot of folks complain about the wolf stuff. So if you are getting good ammo like alexanders you are counting on one company that hasn't been able to keep up for some years.

I have both just to be safe, but I don't hunt. I choose the 6.5 instead of a .308 AR since the cost is 3 to 4 times the amount, plus I already have other .308 battle rifles.

I do like that the .308 ammo is readily available and still be used by our warfighters though.

I guess you want to add up how many rounds you plan on using any of these and use that in your selection.

Get the AR10 with an 18" barrel.

I personally went 6.8SPC in the AR platform to complement my 5.56 NATO build, and plan on .308 for a bolt gun.
Covers all the bases.
As for the 6.5 Grendel I believe it's an amazing round at ranges above 600 meters (with hand loads) in the AR platform with a 20+" barrel. I did not want a barrel that long on my heavier caliber AR platform rifle build, and would rarely (if ever) take the shot at more than 600 meters anyway. Below 600 meters with a 16" barrel the 6.5 Grendel, and 6.8 SPC is a toss up IMHO so it all came down to cost, and availability for me (along with reported feeding issues).
The 6.8SPC won for my purposes.
If strictly hunting I would choose a bolt gun in .308 with 20" (or more) barrel, and leave the AR's to varmint, yotes, and home defense.
Just my thinking on it.

I'd get the .308 for sure. Mainly because anywhere you go they'll have .308 ammo. This good if your hunting out of some bfe town and happen to need some ammo for some reason. Just my .02

Very interesting view Mike. I dont believe that a .264 dia will necessarily ruin more meat than a .277 bullet, especially considering the fact that different bullets are made to do different things. Choose the right bullet with reputable performance and your good. But thats what should always be done anyways so I guess that issue was solved before I even said it. Plus reloading basically takes care of expense issues. Kind of still puts 6.5 Grendel on top

.308/7.62

As expensive as 7.62 is, 6.8 is even worse.

Mozzetti

That is for sure. All of it is way too expensive really when you are putting a lot of rounds down range and not reloading.

A lot of us are hardly shooting much anymore.

6.8 SPC isn't ballistically different enough from 7.62x39 to justify the high price. That could all change if cheap ammo comes along. 308 is in another league all together.

Very true about justifying the price of the round. I hear that the AK round doens't work well in an AR platform...anyone know any truth about that?

I wouldn't mind a set up like this, but that cheap Russian steel cased ammo with all that polymer and dirty powder will still have problems in the AR which will lead to having to buy brass AK rounds.

not true

6.8 spc has similar drop to 5.56, much much much flatter than 7.62 x 39

7.62 commie has twice the drop
