Introducing the Raptor Ambidextrous Charging Handles for SIG MPX. The patented Raptor provides improved ergonomics and functionality compared to the factory variants. Its ambidextrous design allows rapid palm “blading” or finger-thumb charging of the weapon, ensuring the motion is fluid and fast from either strong or support side. The included Support Arm, which replaces the factory spring plate/housing, biases the Raptor upward to minimize scratching or damage to the receiver often caused by the factory charging handle. These variants are compatible with all generations of semi-auto and full-auto SIG MPX firearms. The Support Arm is recommended but not required for Raptor installation, and is not compatible with factory SIG MPX charging handles.
