Let’s chat .300 Blackout for our ARs - it’s a caliber that’s been our Go-To. Honestly, it’s hard to ignore its chops compared to our trusty 5.56 NATO. This thing can handle everything from home defense to mid-size game hunting with a heftier punch, and the kicker - no need to mess around buying extra gear or parts, your current AR setup’s got most of it covered. Yeah, the ammo’s a tad pricier, but it’s every bit available and in every style you’d need.
