Ruger Mini-14 20rd Magazine. I list these as being for 300BO, 5.56 and .233 because they are. This is same mag as the Mini-14 in 5.56 but it has the Words 300 Black Out on them. They do this for guys that have two Mini-14's with one being 5.56 and the other 300BO and it marks the Magazine with 300BO so you won't try to chamber the wrong caliber in the wrong gun. Same with Mini-14 Magazines in 5.56 as you can use them for your 300BO. So if you are having problems finding 20rd Mini-14 mags in 5.56 get these and take the white lettering off. Ruger states these are not interchangable with .223 but they are stating that for safety reasons so some knucklehead doesn't chamber a .223 in his 300B. These sell for $42.95 on the Ruger web site.
If you have the Mini in 5.56/233 and another in 300 Black Out use the labled mags in the 300BO only as it pays to be safe.
