The HK MP5 is one of the most recognized and iconic firearms ever produced. Over the last couple of decades MP5 clones have thrived in the United States market with popular clones from names like Omega and Zenith. This is due to HK not selling a civilian compliant MP5 until the reintroduction with HK SP5. Now, Century Arms introduces their own MP5 clone with the AP5 (Apparatus Pistol).
