Junk tools
The cutter is pure junk. The rivet sets are soft junk.
Must be modified for current ejector.
Replacement Remington ejector appears to be MIM, and doesnt allow either tool access to the front rivet. Concept is good, especially the #1 tool, but the engineering lacks. Hardness is in doubt; files like 1018. Best advice is to fabricate punches out of some sort of tool steel, which should last beyond one use. Product was marginal 30-years ago and hasnt been improved.
Great product idea
The rivet removing tool worked great and got the job done. The #1 punch on the other hand did not. I used a normal framing hammer as I saw in videos of these tools cracking from people using bigger hammers. But still the staking tool cracked after 5 hits. For the price of this kit I would think it would be able to last for more the one single rivet.
Soft and weakly made.
This tool breaks very easily. All it would take for this to be a great tool would be to temper it to actually be able to take the abuse necessary to smash rivets. Brownells, you are not selling a lot of them because they are popular, you are selling so many because they keep breaking.
Just use a Home Depot punch
Bought this set to replace the ejector and ejector spring on my 870. After reading reviews, I was hesitant to buy but couldn't find any other tools on the market so I went ahead and bought this set. The tool for the rear rivet cracked down both sides and did not seat the rivet tight enough. I ended up using a standard punch to flatten the rivet. The tool for the front rivet didn't even fit inside the ejector. After some work with a Dremel tool I got the punch to fit and managed to hammer the first level of the front rivet flat. To flatten the second level of the front rivet I again used a standard punch since at this point the Brownell's punch was cracked. The only reason this gets a 2 star review is that after calling Brownell's, they refunded my money. 5 stars for customer service, 1 star for the tool set.
Did the job. Once.
I had made my own rivet stakes when I first replaced the ejector and spring (2-3/4 to 3" conversion) out of some hardened bolts (grade 5, maybe grade 8 would have worked better), but messed up the job and damaged my stakes. Decided to order this set along with new rivets because I didn't feel like fixing the stakes I made. The stake with the large hole was useless. It didn't set the rear rivet at all, just mushroomed it a bit and didn't go down far enough to actually lock the ejector in place. I ended up using the flat side of the other stake to set the rear rivet and that worked just fine. The stake with the small hole worked for the first stage of the front rivet, but the hole is so tight that after setting the rivet I had to clamp the stake in a vice and gently tap the receiver with a mallet to get the stake off the second stage of the front rivet. All while trying not to break it off. Very annoying. I ended up setting the second stage of the front rivet with a small punch from my regular punch set. After setting the first stage of the front rivet the stake was deformed to the point that I would not be able to use it a second time. I gave it two stars instead of one because the one stake does work for the two stage front rivet, but it was a one chance deal as the tool is now useless. Don't buy this if you want to add it to your tool set.
Replacing Ejector Rivets
Tools worked like they should, but the #1 staking tool split down the middle. #2 staking tool may last longer, but be careful.
Right tool but one-time use
Let me start off by saying that this tool set is adequate if youre just replacing the ejector spring. If you need to replace the entire ejector assembly this set might give you some trouble. First, the tip of the #1 punch was so wide that it didnt go all the way into the ejector channel. This prevented the punch from going far enough to fully seat the front rivet and left the entire assembly loose. I had to grind the tip down a little to make it narrow enough to bottom out on the inside of the ejector and fully seat the front rivet. Second, the depression in the tip of the #2 punch was too deep to upset the tip of the front rivet once the ejector spring was installed. Youll have to use a flat punch that fits the ejector channel or do what I did and just use the #1 punch off-center. Lastly, the #2 punch has really thin side walls and mine split after just a few whacks on the rear rivet. A hardened tool should last for many installs. This was a one-time use tool. This set would be much better if they made some improvements. Its going back and I might just design my own set before my next 870 ejector install.
