Core15® Tac M4 Piston 5.56 NATO / .223 Remington® Semi-automatic Rifle.

For those who prefer the cooler and cleaner-running gas piston operation system, look no further. Made by Adams Arms®, the Tac M4 Rifle's gas piston system stays cool, clean and ready,even after firing 100 rounds in rapid succession.

The barrel is made to better-than-military specifications with a tight 0.0003" tolerance, where the military standard is 0.0010". Core15® also exceeds mil.-spec on hardcoat anodizing, which is Type 3 Class 2, because they control that process at every stage.

By exceeding military standards, Core15 ensures the best fit possible and can offer a more reliable, smoother functioning, and more accurate weapon that will provide you with the peace of mind you deserve.
