It's a fairly simple process.
Step one is , as always, to make sure the shotgun is unloaded. Start by removing the magazine cap, and pull the fore end slide back to about half cycle. Remove your barrel. Look down the front of the magazine tube, and you should see a little plastic stopper with 2 notches in the side and 2 little nubs on the inside of the mag tube. Line up the notches and the nubs, and slowly release the tension on the spring. Remove the end cap and the spring, then turn the shotgun so the open end of the mag a zine tube is facing the floor and tap the side of the tube with your hand. This will bring the follower to the top so it can be removed from the tube.
Field strip the shotgun for the next step. You don't want metal shaving in the action. You will need to drill out the nubs on the inside of the magazine tube. I used a dremel with a carbide bit, and a can of WD-40 to grind mine out. Go slow, and be careful. You can always take more metal oof, but putting it back is not easy. Take your time, and use the WD-40 to keep the area cool and cut down on shavings flying out of the tube. The way to test how close to done you are is to drop a shell through the tube with none of the internals installed. If it falls out the end when inserted at the receiver, you are good to go. If not, keep cutting.
Installation is a simple process. In the extension kit you will have a tube and a spring. Set them aside, and clean the inside of the magazine and receiver out before installing anything further. reassemble the receiver and the action, but not the barrel. After the tube is cleaned up, insert the follower, followed by the barrel, new spring, and the mag tube extension.
As to the other question, I can only talk about the ATI one, as that is all I have ever installed or used. I installed mine about 6 years ago, and I do not baby my guns. It has survived several deer and coyote hunts and a couple of bumps on the night. It works well enough for me to rely on it.
