Mikr is correct. 223 Rem, and 5.56mm look the same, but the 5.56mm i.e. M193 is loaded to 60,000 cup, where as the 223 Rem is loaded to 50,000 cup. The mini can shoot either, as it has an A2 military chamber.
Q3131 is made in Independance, Mo. at the Federal Lake City Plant. The Q3131A made in Israeli. Both shoot about the same, and both come in the Winchester USA white box.

The Winchester seems to shoot well in most mini's. My mini likes them. I would suguest getting a couple of boxes of each to see which your mini likes. If they shoot the same, go for quantity on the cheaper one. Each rifle is different, yours may or may not like winchester. Better to check it out before buying quantity.
