“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

The MCX Spear is a feature-rich rifle with a comfortable grip, adjustable gas system, and a fully ambidextrous setup. The Sig Sauer MCX Spear is a great choice for anyone looking for a modern, reliable, and versatile battle rifle.
“The DDM4ISR is a .300 BLK integrally suppressed rifle from Daniel Defense. It sports a 9 inch cold-hammer-forged barrel with an overall length of 16-inches. This gun features a Keymod handguard and handles just about as smoothly in a shoot house as it does out on the range. We had no problems whatsoever during our testing. This rifle loaded, fired, and ejected perfectly. The grip angle may feel odd to some, but overall it’s great once you get used to it.” – John C.

“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
