It can be used with any caliber an AR-15 upper/lower receiver can be set up for and all it would require would be a change of buffer weight. The buffer included with this brace is a standard 3 ounce carbine weight so it can be used with .223/5.56, but any other caliber and even some .223 setups will require a heavier weight.
