You'll start by unscrewing the magazine cap fron the end of the magazine. It's the knurled knob that also holds the barrel in the receiver. The forearm slides back and forth on the magazine. Gently pry out the spring stop once the cap is off. The spring and plug/follower should just fall out when the weapon is held down, but if you're not holding the barrel, it'll fall out of the receiver also. Some magazine plugs have molded weak points that allow you to break them off to increase the amount of ammo in the magazine. A large pair of pliers with padded jaws may be needed to break the cap loose. Brownells carries weapon specific tools for gunsmiths and they sell to civilians.

Take the plug out of the mag. unscrew the cap, pop out the spring stopper with a screwdriver. remove the spring and plug. Put the spring back in without the plug.
To remove the plug on a Remington 870 series all you need to do is unscrew the cap on the end of the magazine tube. Carefully because it holds in the magazine spring. the plug is the rod that is inserted in the spring so it cannot compress fully to limit capacity so just take it out and screw the cap back on (the cap compresses the spring) and voila. takes about twenty seconds.
Remove the cap from the end of the tube and be careful of the spring which is under pressure. The plug will come out with the cap.
