This MPA30T Defender is a top-cocking configuration with a robust steel receiver and matte black finish. It is a closed-bolt, semiautomatic, simple blowback MAC-pattern derivative with factory MPA Defender shield rollmarks and a Comer, Georgia address.
The 4.5-inch barrel is threaded, and the pistol ships with two 30-round magazines for a 30+1 capacity. A rectangular ejection port is located on the right side of the receiver.
Controls are straightforward, including a top-mounted charging handle and a left-side safety/selector. Sights are fixed iron units with protective ears front and rear for durability and quick alignment.
Ergonomics and build are set up for confident handling: a wraparound textured polymer grip with finger grooves, a short accessory rail under the front of the receiver, and all-steel upper and lower receivers with a matte black finish.
