The difference is the imprinted caliber label. Dimensionally the same its just labeled 6.8.

The 6.8 SPC uses a standard 5.56 lower. There is not a receiver specific to the 6.8.

Thanx guys,

Les Baer makes a .264 LB upper that is guaranteed to shoot .5 moa or better. I haven't tried it, but I've read that the catridges (6.5 grendel and 264 LB) are the same, but the chambers are cut a little different.

I mention it because I think it is worth looking into if you are thinking about going the grendel route, however I haven't looked any further into it and don't intend to unless I get the urge for another AR project.

Les Baer Custom Inc.

You might be able to check with Mark at Short Action Customs | Your Foundation for Precision as well, I've seen some of his 6.5 AR's on the web.

Happy Hunting

Thanx, I thought I'd done my homework, but that one threw me for a loop.

You might look into the 6mm/223 (6x45). It uses the standard .223/5.56 AR mags, the same bolt as the .223/5.56 since it is a .223 necked up to .243.

It will handle hunting bullets up to 100/105 grains as long as you use a 1:9 twist.

I am building one right now.

I hadn't even thought about something along those lines. I'd kinda like something that I don't always have to handload for. But then again, the way ammo seems to vanish with any AR, handloads will probably be all I can afford to shoot anyway.
