What is required to slap a 7.62 upper on my AR lower? I assume new upper, bcg and how do mags work? Assume different mags?

7.62x35 (300BLK) will fit and will run the same mags since it shares the 5.56 parent case.

7.62x51 (.308 Win) will need a new lower as well since the magazine well is larger. Plus it uses a stronger buffer and buffer spring in the lower.

.50 BMG upper will work with .223 lowers.


Get one shot but it isn't like you need to worry about the vitals.
