PARA complete magazines are a narrow listing built around Para Ordnance frames. The MBX Extreme 170mm Complete Para Ordnance-only style 9mm magazine targets Open builds that need maximum capacity, and the MBX Defender Series PARA carry magazine covers shorter setups. These are not interchangeable with STI or 2011-pattern bodies, so confirm your frame before ordering. Check the Para base pad listing for pads and extensions that match your magazine length.
