With the research I have been do prior to building/purchasing my 1st AR, are there any advantages of building a .223 vs.6.8?


6.8 has a lot more stopping power and I am not using the rifle for competition.

I will probably build/buy one of each but if you could choose one, which one and why?

For your first one get it in 5.56x45 save the extra money for ammo and just shoot the hell out of it, then once you know what you like in your AR's built your 6.8 the way you like it. I made a similar mistake, I built a specialty chambered AR before a standard one.

Just look at the cost of ammo, 223 is a whole lot cheaper than 6.8 and there's lots of talk about both on the forums just search around.

On the same note, thats why I build a 9mm AR also.

If you are thinking to build both 5.56 & 6.8 then start with 5.56. Just becareful as to which range you go to. Most range wont let you shoot bullets with steel in the tip, its a fire hazard. When you buy ammo take a magnet with you to test out the tip of the bullet. The casing don't matter as long as the bullet isn't metal.

I am not to worried about the cost factor so much as to the which is a better round.

I plan on reloading so I will hopefully save some $$$$ in the long run.

.223 if you are planning to play.

I went through the same dilemma when I bought mine. Now i am glad that i went .223. It is a fun gun to shoot and I will blast through 200 to 500 rounds in a sitting. The other reason i am glad I went .223 is that my AR is not something I am going hunting with, nor am I shooting 500+ yards with it. (that is what the 700 is for) So in my book the larger round is a waste.

BTW that .233 round is potent when it goes through something. Not a stopping power round but one that incapacitates for sure.

Just my .02

.223/5.56 has stopping power with the right round like some Hornady Tap or something similar. 6.8 might not be the best alternative the 6.5 is far superior in many ways even to the .308, basically I would get something more common to begin with. Buy some 5.56 HD or zombie rounds and buy ammo to be proficient with and practice you'll save money too.

Well what do you plan on doing with your rifle? Are you going to hunt? If not, go with the 5.56. If you are going to hunt at all, go 6.8. And if you decide to get a 6.8, get an AR15 Performance upper receiver.

But first, tell us what purpose you want your rifle to serve.

I have both the 5.56 and 6.8. They're both great guns. The standard 6.8 bullet is twice as heavy as the 55gr. 5.56 so keep that in mind if you're hunting and want the extra stopping power.

You should really do some more research on that.

6.8 vs 5.56/223?
They are both deadly.
The 6.8 will fly fruther (not that much further).
It certainly will have a somewhat bigger punch.

I'd still start with the mainstream, then work up from there.

don't mean to highjack the thread but does it make sense to go 5.56 the 7.62?

Start with 223 and when you like the AR15 enough, you can always acquire another upper in 6.8 or trade your 223 upper away. You can also keep the 223 for lower cost training.

.458 socom and the .450 bushmaster are great beowulf alternatives since ammo for both is easy to find and actually get.

Stopping power is great. But there is no such thing as a reliable one shot one kill in the CQB world either with 5.56mm or 6.8SPC. Murphy is alive and well, and its going to take several shots to do the job. So you have to take a lot of other things into consideration, such as recoil. 6.8 has a lot more recoil making it a lot slower for getting back on target and slower for engaging multiple targets. That in itself could get you killed. So the same old argument applies. Since I have no idea how badly I will be out numbered, the ability to engage as many targets as fast as possible is more important to me that the slighly increased knockdown power. Others clearly feel differently.
