for building a 7.62 upper is the upper receiver any different? I know i need a 7.62 BCG and barrel, but can I use a standard ar15 upper ?

No, assuming you are talking about a .308, it's an entirely different animal. Uppers, lowers, bolt and  bolt carrier group, all different from the AR-15.

If you are talking about a 7.62 x 39 then yes, only the bolt (carrier is the same) and barrel are different from a 5.56.

ok thanks.  Yeah I left out that important part.

Was thinking of building a 7.62x39 .  

I have an extra upper and would like to shoot something a littler bigger than the 223.


So I just need a 7.62x39 barrel, bolt, and magazine,  thanks!

Palmetto makes nice x39 barrels, they sometimes have complete x39 uppers.

And go with the C Products DEFENSE aka CPD mags.
