If you re going to replace it, you will also need front and rear rivets, and you may as well replace the spring while you are at it. It will also involve re finishing the gun. The front rivet is stepped, the first step is to secure the housing, and the second step secures the spring. Brownells sells everything you need including the specialised punches. Almost any gunsmith should have them. You could also give Casey at Tacord a call, he specialises in 870's. You may also want to ask how much to do the job, since the punches come to about 50 bucks if I recall. It's a 20 minute job tops once you know how, but can be a pain the first time you do it. If it isn't affecting locating your barrel, and everything works, you may just want to leave it too
