Has anybody ever heard of the ERA Firearms Company out of Brazil?

Humm, John's info is interesting, didn't know that. thank you sir. I have a Stoeger Coach Gun in 20 gauge, 20" modified/improve cylinder fixed chokes. I bought it to replace my other early season " Grouse Gun ". Grouse season begins early, leaves are still on the trees, and you need to be quick, AND not get your barrel hung up in the clutter. My other little double gun had become just too valuable to be beating around the woods, in rain, freezing rain, and snow.

First thing I did when I got home with the new gun....well I took it apart of course. LOL It had an oil finish on the wood, and I like the classier high gloss to show off the grain. Took all the wood and slopped Tru Oil right over what ever was on there. !9 years now and the finish is still good as the day I put it on.

Actually for $200.00 new I am still quite impressed with what that little gun is. First I noticed OMG, the polishing work inside the bores is SPECTACULAR. Most shotguns you see, ring after ring down the entire length of the tubes. This is polished like a mirror the entire length no rings, just beautifully shiny. Cut Checkering on the wood. Yeah, double triggers ( my other gun had a single selective ) but, not bad triggers. The stock is a full length adult length of pull on a tiny little shotgun, so it points well. The ONLY cheesy thing I find, is that the barrels are Brazed together, NOT silver soldered as normal. So looking at the muzzles, you see the gold brazing, I colored it black.

Now V_G I found a problem with mine. I suggest patterning that gun. Mine was suppose to be Improve cylinder and modified. Both tubes fired the same pattern. Appeared to be a modified sized pattern. So I did some fixing. What I believe was the cause was the polishing inside the bores. TOO smooth, and the wad was NOT separating from the shot as the shot left the barrel. So what I did was to put a section of heavy sized cleaning rod end into my rechargeable drill. Put a Bronze bore scrubbing brush in the cleaning rod. I wrapped the bronze brush with a piece of cloth backed flint paper. ( like sand paper but, flint for cutting ) I carefully ran that about 6" inches in and then more right about the last 3-4" in the choke area. You MUST be very careful of two things. First watch how much heat you are causing. And MORE importantly you MUST be very careful NOT to change the point of impact. Any out of round, and too much on one side and your barrel will not hit where you point.

Mine worked out without problem. You can check the point of impact and your pattern again to verify your results. A little " Do it yourself " gunsmithing, a tad left over from one of your previous questions. I actually like my little Coach Gun, have taken it to the Skeet range often. The guys tease. They always say they hope I got a good deal on the thing, cause they only sold me half the gun.

Added : I only roughened up the improved cylinder barrel ( Left barrel, front trigger ) to open the pattern, did NOT touch the modified tube. So don't take a chance of goofing up both tubes.

Guessing you mean EAA (importer company) that imports firearms from around the world, including Brazil.

Built by E.R. Armentina for Stoeger which is now owned by Benelli.

Found online.

Time for you to learn about "keywords".

Edit: Armentino is the name
