Got a question for you gunsmith guys, Teach or anyone else that may know. How do you disassemble the Breech block on the 1873 Springfield Trapdoor? I want to replace the latch spring and can't find any info on how to remove the latch from the Breech block, it doesn't have the screw holding it in like the

    Way too late to ask Erskin Allen.
    Good thing this place has the guys who know.
    My thoughts are generally clear. My typing, not so much.

    I've got two of them, but never have had to take one apart. Video should help.

    Those videos will not help, I have a different design.
    This is the one from the video with the take down screw.

    This is the one on mine without the screw.

    Is that an original 1873 or one of the H&R replicas?? There might be pin holding it in place that was polished and blended in with the other metal!

    Its one of the H&R's, I sure can't see any place where a pin was blended in. I think I read somewhere you can replace the Breech block with an original, I may look into that.

    Numrich shows a cam latch retaining screw for the H&R.
    Here's a good sight for trapdoor info.

    Just won an auction for a complete 1873 dated breech block, no pitting but I will need to polish and blue it.
    I got t for $64 which is a steal. I think this will be the answer to the H&R crap latch.

    In case the original part doesn't work, try prying the latch outward as you rotate it through its range of motion. It's possible that one is retained by a detent ball and spring riding in a groove. Don't get too energetic with it, but sometimes a low-tech solution is all that's needed.

    Polish, don't blue, at least find out how much it is worth first !

    Took some fitting and some cussing but she is installed and works great. Dry loading and ejection is good, empty case with primer test fire good, now I just need to take it to the range for a live fire test. Hopefully all is good and my auto eject issues with the trapdoor popping open are gone. I have always really liked this rifle and had it for several years but never had the nerve to get a Springfield Breech Block and go to dremmeling everything.

    I wish the bluing would come out better but I'll keep working on it and if it never matches completely; well as long as it shoots good I don't really care!

    With the new (Old) parts installed.

    Thank you sir, I was getting nervous, I had to cut out way more than I thought I would but the Springfield latch sets a lot deeper into the back of the receiver which was the problem with the H&R latch that was smaller, too shallow and would not hold well under recoil.
