After years of slowing destroying my magazines by cleaning them during the break down. I found this tool that works and it works very well. I went and got the combo with the brush. The brush has a pin that is made of steel that works great to break the frame down too. Then even better the whole kit is made in the USA to boot. I give the tool an A+. I have new magazines that were hard to break down this tool made that work a breeze. Here is the link.
