My friend has broken ejector spring on his Remington 870 recently. That is why we have recorded a video to show how to replace broken ejector spring on Remington 870. Also, you will find instructions and photos below.

First of all, you will need the right tools. The easiest way to fix the ejector spring is to get an ejector spring rivet cutter from Brownells.com. Hopefully, you will not need the complete rivet staking tool set and other tools such as two special punches.

The process is fast if you can re-peen the existing front rivet, if not, you will need to have more tools and will have to spend more time and efforts to remove the old rivet completely and use the new one.

Re-peening should be done using small punches or punches from the Brownells Remington 870 Rivet Staking Tool Set.

    I have been teaching unarmed self defense for nearly 30 years now. And as a combat vetreran firearms as wellfor almost as long. People come from all over the planet to train in my methods for two decades plus.The Iiareli’s have even adopted my training methods.

    I have been using the Mossberg 500 for years in one module of my courses. After a few decades they wore out. and I replaced them with the 870 after after my Massad and US piolice, DEA students and other recommended them so highly.

    But having bought them they jam so much ,. all failures to eject, that is shells hanging up in the breech, that I am ready to shitcan them all. I am totally amszed at this too.

    Can you please give me any explanation for this failute, is ther any known remedy?

    I am going back to to the Mossberg 500 because pepole’s lives depend on my training and instruction. I just can’t understand what is happening here. Why are all my 870′s failing like trhis so consistently?

      I know this is an old post, but here’re my thoughts on why you may see shells sticking in the chamber:

      1) Were the new guns cleaned and inspected? 870s tend to come from the factory with a protective coating of oil or grease, which can effectively reduce the interior diameter of the chamber (especially if it collected dust in a gun shop or warehouse for a while before being sold). It’s highly recommended to clean and polish the chamber of a new 870 before taking it shooting for the first time.

      2) Were the new 870s put into use right out of the box? Like many guns, 870s are not at their best until they are broken in; and they only get better with use. There’s a reason old, well-used 870s are known for their silky-smooth actions. As they come from the factory, 870s (especially the budget-level models) can have roughly-finished areas inside the chamber and receiver that can increase the chances of hang-ups. As the gun is cycled and fired, these rough areas will be smoothed down, and the gun will function more smoothly and reliably. Polishing the chamber as mentioned above can help this process along.

      3) What ammunition are you using? Cheap, steel-based target loads (especially Winchester Universals, which have a reputation for jamming all different kinds of shotguns) are more likely to over-expand and hang up in the chamber than brass-base shells or heavier-built steel-based shells, due to a combination of steel’s poor recovery (shrinking back down after firing), and the thin metal some manufacturers use to try to save money. Some brands are better than others, and there really isn’t a price difference between the good stuff and the crappy stuff (in fact, the good-quality target loads I buy are cheaper than the crappy shells that choke guns). When you combine cheap, poorly-built shotshells with a new shotgun that isn’t broken in, these hang-ups become far more likely.

    Short stroking is the number one cause of stove pipes, cheap ammo doesn’t help of course. good luck, J.R.
