I'd offer to trade you pmags but I don't know if hexmags work well in Blackouts or not.

The difference is in the followers. If you look at the pic below the outside mags are 5.56 and inner black one is 7.62x39R and the blue is 6.5 Grendel you can see two differences - there is a shelf on the 5.56 and the slope starts sooner. But the 7.62 and 6.5 work fine for 5.56 is going the other way that has problems. One can always buy replacement followers on-line - I've done so to rebuild worn out ones.

I just ordered 2 300 blackout hexmags thinking they were 5.56 mags for my ar-15 will I be able to load and shoot my 5.56 rounds in the dedicated 300 blackout magazine?

Absolutely
They will load and feed without issues

I'm not buying the whole, "I accidentally bought the wrong mags" story. They don't make a mag exclusive to 300 blackout. They only make 5.56 mags that work with other cartridges. Straight from Hexmags website:

CALIBERS:*.223/5.56x45mm, .300AAC Blackout, .458 SOCOM, .50 Beowulf and more

Build a Blackout upper problem solved

This is the correct answer.

I just ordered the wrong handguard / forend

As established above, the only good solution is to build another rifle

Mag-Pul makes AR mags labeled for .300 Blackout
Cost the same as the AR mags Their angle is something about the follower, but I've never had any issues with using .300 BLK in the standard AR mags.

Not trying to be a dick (although it seems to come naturally), if the OP had said Magpul I would've gone to Magpul's website to see what the OP was talking about. They didn't. They said Hexmag. Based on the topic of this thread, Magpul is irrelevant.
