brand new Airsoft hop up rubber 60 degree which is perfect for most setups exactly the the maple leaf Mr different composition sometimes with certain hop units the lips need to be filed down as there quite long beat way to tell if they are too long is to looks through the BB chamber if you can see the lips poking though there too long I take no responsibility for this being done incorrectly if you would like any information please message Roberts Airsoft tech thanks for looking please view my other items
