Can I attach a 6.8 SPC upper to my regular Rock River LAR-15 Lower and not worry about cycling issues? I want to acquire a 6.8 SPC upper and it be interchangable with the lower receiver that I already have. Is this possible?

I did just that. Stag 6.8 upper to Mega lower (previously had Rock River .223 upper)...works fine.

Re: 6.8 SPC question
Just needed to hear it from the folks that have done it and had success. I was pretty sure that it could be done but I also thought that there could be problems with cycling or wearing out buffer springs.

Yeah, I got that part. The one I am looking at comes with mags and 200 rnds.

Just make sure it comes with the bolt - I've seen a lot selling recently that don't and that is a hard find sometimes. Some of these guys on GB (and I don't know where it is you're getting yours), don't even mention that it's not a part of the package.
