Matrix Arms AR-15 Dual Side Charging Upper & BCG Gen 2

One of the key benefits of the AR-15 platform is the ability to change calibers by simply swapping a complete upper assembly or by replacing the individual components—the bolt, barrel, and upper or lower receiver. Matrix Arm’s 5.56 Side Charge Upper / Bolt Carrier Group 2.0 will allow you to optimize your AR-15 Bolt Carrier Group for use with 5.56 NATO rounds while also giving you the flexibility to choose between a Standard Mil-Spec Rear-charging handle or to convert it into a Side-Charging Handle.

Our innovative Matrix Arms 5.56 Side Charge Upper / Bolt Carrier Group 2.0 combines standard Mil-spec features such as a flat-top rail, Rear-charging handle, forward assist, and dust cover with a left-facing forging cut-out that gives you the option to convert to a Side-Charging Handle if you choose to go that route. The Matrix Arms 5.56 Side Charge Upper / Bolt Carrier Group 2.0 comes fully assembled with the Bolt Carrier Group (BCG) 2.0 included, ensuring that your project goes as smoothly as possible and that all components fit properly and perform their respective functions as you’ve come to expect from our products.
