Made by Madbull, discontinued many years ago. Features a quick disconnect system. The flash hider looks super long, but the threading is actually deep inside so it adds the same length to your gun as any other birdcage style flash hider. The flash hider has positive threads, but a + to - adapter is included and fits up inside the flash hider and only add .5 inch to the length. The paint has some small scratches here and there. But there's no major damage whatsoever. It's in great overall condition. Price is shipped and no trading.
