I tried searching for this but no luck. Anything wrong with slapping a 6.8 upper on a 5.56 lower other than it looking stupid or some thief stealing my rifle and putting the wrong ammo in it? I see a lot of lowers marked "Multi" and haven't ever seen one marked 6.8. Just temporary, want to order a Bison Armory upper but don't have the cash for a complete lower so would just swap it onto one of my existing 5.56 lowers for the time being.
ETA: Or if I'm just an idiot please say so. I've never looked into 6.8 until about 20 minutes ago.
Same lowers for both calibers, only 308 needs a bigger magwell. You can have 5.56, 5.45, 6.8, 22LR, 9mm (with a block), and plenty of other calibers operating out of the same lower you already have. Won't look any different and will run just fine.

Yeah I hadn't looked much into it really, was planning on making a .308 but I just don't have the cash to built it like I like it. This will give me a somewhat larger caliber to slaughter hogs with and a good round to set the kids up on some deer, bigger than .223 anyway, so it'll have to do for now.
