I have not used his EZ tool, but purcased one of RB's quick releases fo my 10 ML II and it does well from what little playing I have done. Only instaled it to test it out, and have not actualy caried the rifle anywhere with it installed so I guess that I should admit that I have not actualy used it. Only a qhick test to see how it worked. I still do not understand wht Savage was not smart enough to continue using the bolt release that the had on the original 10ML. It made bolt removal much more convenient which kinda eliminates the need for the EZ tool.
