It's simple enough, you replace the trigger spring with Rare Earth Magnets. Specifically you need 2 packages of 1/8" Rare Earth Magnets from Radio Shack; there are two magnets to a package and you need a total of four for this mod. I don't recall specifically but I believe each package cost me $1.29 USD. The package part number is 64-1895 and looks like this:



Going back to our High School science days we know that magnets have a North and South pole. North and South attract each other but North and North don't, they repel each other (and subsequently South and South repel each other as well). Since this is replacing a spring that repels the trigger from the frame we are going to install the magnets to do the same thing:



As you see the magnets are double stacked on each side. Stacking them increases the magnetic field (and repulsion from the opposite stack). Super glueing the stack may not be necessary but it will prevent the magnets from throwing each other around inside my trigger! I also super glued the magnets to both the trigger and the spring cup in the right side trigger frame.

I shaved down the nub on the nose of the trigger to be flat but still existent so that I could undo this mod if I didn't like it. This will also help the magnets get closer together when the trigger is pulled which will increase the resistance and assist in keeping my RT in the sweet spot.

Also notice that the nub was shaved at an angle - when the trigger is pulled the magnets will be parallel at their closest point to each other. Is this necessary? Probably not but I'm a bit of a perfectionist...



The end result is a far lighter and smoother trigger pull. It didn't really help me with my RT too much. It turns out that I preferred the stock trigger spring. It has enough tension that it actually makes it easier to keep in the sweet spot.
