My knowledge of firearms is more sophisticated than being able to accept your argument that the .223 in an AR type weapons is not powerful.You are the one who "know very little about the topic".
While the .223 is more powerful than a rimfire .22, the POINT is that the .223 is one of the weakest bullets made.
It is NOT powerful, and in fact it is illegal in most states for deer hunting precisely because it is not powerful enough and not likely to kill cleanly.
or that it's a 'weak' bullet! What in hell makes a bullet weak?
It's in fact one of the world's most efficient weapons for killing people. and 'no', it's not a good choice for deer so you're right about that.
And fwiw, the pink AR would also appeal to the wrong people (women) in my honest opinion.
