Mag-20 300 bo

Can I use a 300 BO mini 14 magazine with 5.56 or does it have block in it for the shorter 300 BO cartridge? I have a chance to buy one for a decent price but haven't seen one in person to compare.
There cannot be a crisis next week. My schedule is already full.

What 40nascar said.

Ruger marks the mags with "300 AAC Blackout" so people won't inadvertently load a mag full of 300 BLK into a Mini-14 chambered for 5.56. That's the only difference.

I have a 300 Black Out marked 20, same as my other eight 20 rounders.
