20'' or 24'' AR-10 Barrel Accuracy ??

A good friend of mine purchased an Ar-10 with the non fluted target barrel he likes the 16'' barrels . I may trade with him , he is going to let me shoot it as his is used . I want to make sure it is in good condition so I plan on throwing a scope on it and shooting some 3 shot groups with it at 100 yards . I only have store bought bullets . What kind of accuracey should I exspect ? I dont want to trade if it is shot out .

I plan on shooting this rifle out to 1000 yards coyote hunting,deer hunting maybe to 800 yards. Will this barrel work ?

Another question . My bolt and barrel is brand new so could I just trade my barrel for his barrel and keep my new bolt ?

Thanks for any advice . I dont know anything about these styles of rifles ...
But I have been bitten by the black rifle bug

And stop! need more info, there is NO STANDARD at all for AR variants in calibers other than 5.56mm NATO. So given that info we can proceed.

Not sure I understand what you mean ?
What kind of Info are you looking for?

Make Panther Arms .308 ...
Will eventually hand load 175 SMK.
but right now I have 3 different kinds of factory Ammo One box is suppose to be a match load.
Let me know what Info you need .
I am looking for a ball park estimate like 1'' Moa at 100 or 1 1/2 Moa at 100 yards. I really have no Idea. I guess if I put up a 2'' orange sticker on a sheet of copying paper 8 1/2'' X 11'' and I have 3 shots scattered all over it then I will pass on the trade .
As for the bolt , I need to know if I can switch my new bolt out of my upper and run it on the target upper that I would be trading for.
Thanks

Once again, we need to clarify. Are you wanting to trade an upper or just a barrel?

I try an relate these fact to everyone in my post, in the world of AR rifles there are some constants or Standards. In the AR world Armilite Rifle, AR is a name owned by the Armilite corporation AR15,AR10, SPR (if you don't own an Armilite technically you don't own and AR10). There is a standard for the M16 family of rifles called "MIL-SPEC", it's a manufacturing, material, and size standard. Some companies adhere to this, some exceed it and some claim it but do not provide it (marking tool). This standard on the M16 family in no way apply's to the larger variants of the Armilite AR system. What all this means is if you own one of these rifles it may or may not be interchangeable parts wise with a rifle from another maker. Some of them use different magazine designs and still others use different upper and lower receiver designs, not to mention bolt carrier groups. There are three patterns that I can think of off the top of my head the Knights-sr25, DPMS and Armilite.

This is why I asked the question I did, you may not even be able to swap uppers. If your rifles are incompatible with one and other you cant swap. The other poster mentioned the barrels, this is because that "should" be the one common part. You may be able to swap barrels.

All this said the buffer spring and buffer you have in your rifle will have to be swapped with his rifle and this is only possible if you have the same length receiver extension. So what I need to know is what you have and what he has, what stocks you guys are using etc. As for the barrel accuracy you may see an improvement due to the weight of the system, however the 308 Winchester is not sensitive to changes in barrel length. In my opinion the added weight of the barrel you are talking about is not worth it, as the 16" barrel with a 175g SMK will get past 1000m before it drops through the trans sonic range.

If you really want a different barrel buy one, in the length and profile you want. Rainier arms is a good source.
