20" 6.8 SPC upper receiver

You might look at a 7mm-08 AR-10 if you're dead set on a longer barreled rifle (yes, it's a .284 bullet, not a .277 bullet). The 6.8 doesn't have a ton of case capacity to make use of that longer barrel, IMO.

I don't think that will make or break my decision. I just know I'll eventually want a really long AR based rifle.

Then I think, eventually you'll want to look at an AR-10 for a larger bullet AR. To make the most of those bigger bullets and longer barrels, you're going to need to be able to build some pressure. It's tough to do in an AR-15 platform, but not impossible.

You know how it is, these guns are like Lays potato chips, you can't have just one.
