“Designed for rapid deployment from concealment, the MCX Rattler packs a punch in the .300 BLK configuration. Coming in at 5.1 pounds empty, sporting a 5.5-inch barrel and folded length of 17 inches, the MCX Rattler is definitely compact enough to be carried anywhere.” – Joshua Fox

final verdict
“The MCX Rattler is still an absolutely fantastic gun when shooting supersonic ammo. It is small, and concealable in any standard backpack. Not to mention, it packs a punch with a 30-round magazine that can reach out to a couple of hundred yards. Plus, it just looks really cool. Just make sure you pay attention to what ammunition you purchase and feed it if you are not running it suppressed.” – Joshua Fox
