Dont waist your money on these they are not made like they used to be!! took oring of so i could get out the piston and the little oring ripped on very sharp threads.basically a little oring holds the piston in the detent ,wich also puts more unwanted tension on piston ,more than just magnet.
if your feeling crafty get the hybrid ones and magnet mod them it will turn out better than this new version.common screw driver to install and remove.scratches with screw driver easy!its not like the pictures of the old version where you can take apart on face side .ordered straight from company and they sent me just two of the no vision side detents so the vision covered side is to short!
Very expensive ,very cheaply made ,should give extra litlle magnets incase u lose wich u will cause they just stick on flush outside of detent. like i said very expensive for what u will get for 50$ shipped
