Guarder Enhanced Loading Nozzle for Airsoft Gas Blowback Pistols (Type: Tokyo Marui M45A1)

"This is not a blowback unit. it is just the shell of one it comes with no internals whatsoever even though that is not listed anywhere on the page. evike's customer service is the only thing worse than this I have emailed 3 times to try and get this rectified and have never gotten a single response. DO NOT BUY THIS
