How many Rounds before changing Mag Tube Spring?

[HK_P7]

How many rounds can you cycle before your Remington 870 Mag Tube Spring wears out?

Also, if you leave the 870 loaded, how long will the spring last?

i dont know after how many rounds.....but wilson combat suggests every 6 months if you keep i loaded.

Hard to say. I have been shooting my 870 for over 20 years. Skeet, duck hunting, quail and dove hunting, target shooting, and just plinking. I am on the same spring still, and the gun functions perfectly.
I would expect those that sell mag springs to recommend changing them often

Realistically? Probably last you a lifetime. All the ancient 870s I've seen, barn guns or farm guns or ones which have seen really heavy use, have also often stayed loaded for months at a time... and exhibited no problems at all. Who knows how many tens of thousands of rounds went through them... the spring is still fine.

I have never changed one, and never had a problem. I would offer that you should change it every 100K rounds whether it needs it or not if it makes you feel better.

Springs in compression/de-compression don't wear out. What wears springs is constant use. So if I were in the replacement spring biz, I would suggest yearly. Otherwise I guess I would wait until there was some feed malfunction that might be spring related or a rusting spring. I think the rule is; if it ain't broke, don't fix it.

The plastic follower in 870s will wear out before the spring will. I had a 1911 mag fall behind my workbench in my old hose and it stayed ther until imoved out 13 years later and found it. Worked like a charm. all 7 round with no problems.
