    "This thing is absolutely necessary for Maple Leaf AST buckings if you want to get the most out of your hop-up. I was using the stock nub provided with the AA hop-up chamber and was getting some inconsistency since it didn't provide the proper amounts of pressure along the AST bucking. Once I replaced it with this all the issues disappeared and my gun firing great. Wish I had known about this sooner.

    "It's a hopup nub. It gets the job done.

    "Good bucking, I combined mine with the 75 Maple leaf AST bucking. I gained about 30 fps in both guns from the better air seal. And both shot with near pin point precision. A couple things to look out for though, make sure everything is lined up, since this is a concave nub, if it isn't straight on, it will make the bb fade right or left. Also, when playing in heavy rain and in and out of water scenarios it tends to lose its ability to hop, not sure if there is a nub/bucking combo that wouldn't though.
