Help With 870 Ejector Rivets

Any advice on removing these rivets? Most of the videos online about removing them seem to show them already removed when they start. I tried cutting just the head of the rivet off, but there wasn't enough to peen it again to get the ejector spring to stay on. So I decided to knock the rivet out, but that's been more difficult than it sounds. Are you guys having it cut it down to the ejector, or what is the best way to get it out?

Also, is there anyway to put it back in without the expensive Brownell's staking punches (which look very cheaply made considering they broke in one of the youtube videos).
 
Take a small dremel tool and grind off the rivet from the inside and then knock it out with a small punch , it will come out easy once the rivet has been ground down enough . You will see a line around the rivet when all the penned part has been ground off . Then buy a new ejector , rivets and the staking tools to replace it .

Go slow grinding so you can see what you are doing and don't worry about hurting the old ejector you are going to replace it . Brownells also sells a rivet cutter with the staking tool set .

If you have to buy all of this stuff it will be cheaper to take it to a gunsmith unless you want the tools for the future .

The front rivet has a separate head for the ejector and the ejector rail. The rear rivet just holds the rail in place. Be careful when staking it that you don't crack the ejector rail when staking it or you will be re-doing it.
 
It is a two stage rivet, the ejector is staked down, then the ejector spring. You will need the staking tools which do not break when correctly used. The interesting part is that the new rivet head sticks out the side of the frame. Put the rivet in place and before installing the inside parts, scribe a line around the head. You then grind and polish down the head to this line so that it matches the curve of the receiver and finish with cold blue. If you install everything first you will have to grind down the rivet from outside and I guarantee will have to refinish the receiver. GW

Addendum: when setting the new rivit, be sure to back up the head on the outside with something hard so the impact will swell the inside and not set back the outside.
