Ar 6.8
Does anyone know if a 6.8 upper will fit on a regular 5.56 lower? If yes, do I need to make any modifications to the lower?

yes to the first no to the second, put pull the pins take old off install new and replace pins. you will ned 6.8 mags for it.

6.8 what? 6.8 SPC? Yes, it will fit on a standard lower. The magazines will work, but will take less rounds per mag.

You will need the new upper and yes it will fit your lower. You will also need the 6.8 bolt and mags. after that you are set to go.

The forum is on the money! All you need is a *complete 6.8 SPC Upper and a Magazine and you have a full fledged 6.8 SPC Cal. Rifle.
Also for example if you wanted a 458 SOCOM? All you would need is a complete 458 SOCOM Upper. Even takes the standard 5.56/223 Magazines. That is what makes the AR-15 Platform such a great unit. This also applies to other calibers that are available with only the same type installation.
