okay I really don't like how you have to buy a armours tool just to take apart a friggin magazine to replace the spring or anything so I found a alternative way to do it with a screw driver. here is the vid on youtube:http://youtube.com/watch?v=GY2f4Jblx_g
if ya'll could watch and give me comments in youtube or here on if it works on all magazines or not and if I can improve it anymore

thanks!

Well, that's one way.
Personally, I just whack the rear edge of the floorplate with a plastic mallet.
Not very subtle, but it works, doesn't hurt anything and I like hitting things with hammers.

interesting,
but anyway I can make mine better??
