T4R. I remember hearing about one, but I don't remember the name.

Just get one in 7.62. It's still cheaper than .223 and the sucky thing about .223 is that not all .223 rifles will not standardly perform if 5.56 is loaded. You have to get a rifle that both 5.56 and .223. Yes, the calibers are the same but at the same time they are not. It's difficult for me to explain without linking a video. Basically because 5.56 is military and .223 is civilian
