AR Question

[SoCal50Lover]

I have an AR-15 that is .223. In order to shoot 7.62 can you just change the upper or basically you need a whole other weapon?

I've seen 7.62x39 uppers on Midway that'll fit on standard AR lowers. To get Nato 7.62x51, you'll want to start looking at the AR-10 line; that's what it was designed for.

7.62x39 requires a different upper and magazines.
7.62x51 requires a different lower, upper and magazines.
