    Honestly these are so easy to install and just make my shot consistency really rise. I will say be careful as it is easy to accidentally gouge the bucking with the nub if you over do your tdc screw and try to shoot a bunch of bbs. Really though with this I barely have to out any hop even with. 43

    Used in ssx303. Results are amazing but a little bit better than original hop arm
