Howa Mini Action Extended Magazine Catch by DIP Inc

Amazing how much easier it is to work the bolt. Being left handed, the small factory bolt knob was ackward working the action. With the oversized knob, it takes much less stress on my wrist and very smooth. I cut the factory knob off with a hacksaw, faced the cut with a file and drilled the hole for the stud using a drill press & vise. I did have to have a friend TIG weld stud in place. Very minor cleanup of weld and spray paint. Instructions in box are clear and straight forward. Worth every dime to me.
