Because the needs of individuals vary even more than the variety of ARs on the market, it is nearly impossible to identify the “best” personal protection AR; what might be great for one, will be lacking for another. However, when all the measuring, guessing, and pontificating are done, the Spike’s Tactical billet ST Compressor is probably as close to all-round perfection as you’re going to get. Chambered for the .300 Blackout, the Compressor is what’s known as a “two-stamp” gun: You’ll have to have one federal tax stamp for the suppressor and one for the lower receiver, because it is a dedicated short-barrel-rifle (SBR). The gas system on this gun is as radically engineered, the barrel is radially fluted, and all controls are ambidextrous. Everything about the compressor screams, “I’m ready for villains, demons, vampires, and werewolves!” If you want to defend your castle, or carry around the most badass truck gun made, this is the one for you.
