Without using price a a criteria which one would you buy? I've decided against the 6.5 for now due to the lack of ammunition so the 6.8 SPC is my second option. I want to use this rifle for everything from target shooting to deer hunting. Thanks guy's!

5.56 Options:

http://www.rainierarms.com/?page=shop/detail&amp;product_id=2010

http://stores.homestead.com/Laruetactical/Detail.bok?no=100 (18&quot; Barrel: 13.2&quot; Hand Guard)



6.8 Options:

http://www.rainierarms.com/?page=shop/detail&amp;product_id=1849 (This is the one I keep coming back too)

Thats a tough one but if your going to do some hunting Im thinking one of the 6.8s. Out of the 2 6.8s Id go with the 16&quot; from what some of the guys have said about barrel length and proper burn time.

I am a bit confused on that subject. Most of what I have read says you get better ballistic co efficient from the 18&quot;. Question

I thought ballistic coefficient had to deal with the bullet only!

Meant too say better ballistics. Referring to barrel length and velocity's.....

Too bad the Noveske doesn't have an 18&quot; barrel on it.

I hope to get a .308 lower from Quentin and build an AR10 next year, will have to sell my M1A though.

I vote for the Rainier.

Im not 100% sure either. Brandon has done some research on the matter.

Heres the thread where he shares some of the 6.8 info

Randy, I think you're reading misleading information. the more barrel you get, the marginal returns on the ballistics, tend to decrease. The 6.8 and it's design with a 1/11&quot; twist, or a 1/12&quot; twist with 4 or 3 grooves allow for the bullet to perform optimally within a 14.5 to 16&quot; barrel. The velocities out of these two barrels are marginally the same, and with the two, you have a compromise of velocity and terminal ballistics that allow for ethical, and lethal shots at 250-300 yards. Would I personally take those shots, not really. 100-200 yards with an AR in any caliber (even 6.5) would be kept in that range.

I sold my 18&quot; because of the weight issues that I had with it. Even going with a Lite rail and shorter would still make it barrel heavy (prolly cause it was an SPR profile fluted....). Anyway, my plan, is to go back to the 16&quot; that I was running before to build a varmint/deer rifle... it's easy to hump into a tree stand/tripod, and still provide the distance I'm looking for. Then build a 10.5&quot; upper to provide a truck gun option to shoot outof the back of pickups or inside a pickup when spotlighting pigs in our pastures.

If you need any other info or help, pleaes do not hesitate to ask. Stay away from the 1/10 twist barrels in the AR... the commercial ammo will shoot them, but you're limiting yourself honestly to the higher end, more expensive, heavier ammo. 1/11&quot; will give you the option of running 85gr to 115gr.

Thanks Brandon! I am going to have to ponder this a while. I may just stick with the 5.56. The 6.5 is out for sure due to ammo shortage and from what I gather the 6.8 has very limited range compared to the 5.56........ Confused

The 6.8 SPC does have a more limited range than 5.56
However, you can kick a deer in the dirt out to 250m with it.
Very effective round, MOST hunting shots in the US are far shorter than that.

Not necessarily a limited range. The 5.56 is limited to size of game at the same distances... that's the way to think about it. An 80gr bullet (AMAX) will not feed in an ar magazine. So heavier grain bullets are going to limit your capability in the 5.56. Having said that, their velocity and lethality distance is not going to be sufficient for some game animals. I would shoot a doe with a game king out of the 5.56, but not greater than 100 yards, whereas, I would shoot a 100gr accubond or 110gr prohunter travelling at 2700fps out of a 16&quot; barrel in 6.8 at 200 yards at the same doe. Bucks are a little different considering I want to make certain that sucker is dead.

5.56 is not a large game animal caliber. Never intended to be. Some use it for that purpose, though. Your mileage may vary. I'll stick to using 5.56 for varmints and small game animals at the distances we spoke of 100-250 yards, but use my 6.8 for the larger sized game at the same distances.

This is Noveske's SPR 18&quot; that they have in 6.8SPC. If you're looking at spending $1500 on an upper alone, I'd go with Noveske. The quality of the barrel (polygonal rifling is supreme), all high quality stuff, then there ya go.

Here's what I'm shooting for;

Thanks again brother! I'm just going to wait for better ammo availability for the 6.5 Grendel. I want to use Q. D. upper and a 6.5 barrel for my chatterbox build but for now I am going with the Larue Stealth and later when I build the 6.5 I will mate the Stealth upper to a Larue lower....... Wink

I thought he was talking about the Noveske in 5.56, which I found this.

If you are going to try the 6.8, give this place a look. Harrison, who runs it, has done a lot of the research into perfecting the 6.8 round. I have one of his 18&quot; SS uppers, mounted on a Daniels Defence lower.

Good to see you on here Mike. fdx is a good guy, and has been around the 68 forums a while as well.

I've been too busy to post much lately. Hope to change that soon. Lookslike the wife is going full time at work, and I'm staying home for a while.
