Pistol-caliber carbines (PCCs) are one of the two hottest segments in the AR industry right now (the other being pistols), and their popularity extends across several different platforms, not just rifles and pistols based on the AR-15. There are now so many PCCs on the market that you should just assume that anybody who makes an AR makes a pistol-caliber version of it, and you’ll probably be right.
Since we physically don’t have space to cover every PPC in one article, consider this a highlight reel or the CliffsNotes version of the models currently shining bright in this crowded market.
