    "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.

    "I recently bought two of this nub ..

    One for my cqb aps m4 that shoots 395fps I used .25g bb and this nub worker great .. increase the range like 10' and also accuracy..

    The second nub for my ics m4 dmr 535mm inner barrel, 485fps .30g bb and this nub dint work !! The bb will get stock due to the hard nub .. I tried it with different bucking and still does the same ....

    Now I'm creating my own flat nub from Sorbo pads ... It's has more friction...

    Might post resolt if requested.... Good luck if thinking about getting this item ..
