Take one regular mag. Screw the 12 gram tightener IN until it goes completely inside and falls out. Take remote adapter, thread into same hole from the bottom of the magazine until it's snug. Take a wrench and lightly tighten it down. If it leaks when you add a remote (with the magazine out of the gun, the built in valve will still function), snug down a bit more, but don't over do it. Place mag into gun, attach remote to mag, shoot people.
Really that's all there is to it. To switch from remote to 12 grams you can take out the magazine with the adapter, and put in a magazine with a 12 gram. You might need to adjust your velocity settings a touch when switching air sources.
