A .410 A5?!!!!!

    Yep, you heard it here first. I think.

    I inherited my father's machine shop when he died way back in 1977--lathe, milling machine, shaper, etc. I worked on guns to feed my kids from 1975-1980. I have been certified in several welding criteria. And to top things off, I worked full time as a machinist from 1982 to 2004. I built a box-fed Remington 870 in the early 1990s, to include making a whole trigger assembly to work with the box magazines I made. I made my own falling block style rifle that shoots .50 BMG. Everything except the barrel was home made. Heck, I even built and raced a funnybike in the 90s, again building the engine and frame myself.

    By no means am I bragging. Seriously. Just setting the background for my announcement.

    I have decided now that I have been retired for a few years, I am now longer raising my grand-daughter, and I successfully divorced my wife---my bucket list consists of a total of ONE item---to build a .410 A5!!!! I am 98% certain as long as I don't sell it I would be completely legal, and it would be just difficult enough to make it interesting. I already have a couple of Remington 870s in 12/209/.410 so I figure I could use those dimensional differences regarding what measurements would have to be scaled down for the smaller bore, etc, and what dimensions would stay closer to "normal/standard" size, such as LOP, etc.
    The receiver in and of itself doesn't look to be TOO hard, and the wood would be relatively easy. All the internals would be pretty easy too, but the one thing that is giving me some concerns is the barrel. I cannot decide if I want to turn the barrel out of a much larger piece of steel and offset my machining to incorporate the magazine lug as part of the barrel, or simply turn and bore a barrel, then weld on a barrel lug for the magazine tube. The barrel extension will be another major issue. I can easily make it and have it hardened to whatever Brinell number it needs to be, but to "properly" install it is admittedly beyond my current knowledge at this point. Oh well, I'll burn that bridge when I get there.

    I have seen plenty of other people make operable miniature guns-so why not????


    (And yes, it will be a round-grip butt stock, thank you very much for asking.)

    Hmmmmmm.....I never thought about the engraving...........hmmmm.

    Might as well make a 28 gauge too. I’d like serial number 1 in 28

    Bill,
    I wish I had your skill, me too, I will tackle such a project. However, I would do a straight grip and like Justin, I would prefer a 28 gauge. I guess I will have to be content with serial number 2 since he had already chosen number 1.

    The Franchi AL-48 is available in 28 gauge. There’s never been a .410 version of the gun. I’m guessing you’d want to use as many off the shelf parts as possible. The Franchi might be a good place to start.

    Blasphemy!!!! I am preparing and planning on making virtually every part. (Pins and screws excluded because.....well............... just cuz'.)
    And as much as I hate to say it, I can't make any to sell, as the ATF would raise their eyebrows at me. I would have to read up on it, but as I recall a person can make a gun for their own possession, but cannot transfer it in any way to someone else. I will have to read up on the fine print. And, BTW, I am guessing this will take more than a weekend in the shop.

    And, 28 gauge?.........I can't hardly bring myself to jump onto the 16 gauge bandwagon, much less a 28! (Who knows, maybe it'll turn out being cool enough to warrant making a couple of them.) I am going to sit down with the Remingtons in the next few days and start comparing numbers.

    And, without a doubt---straight grip! One of the guys I shoot sporting clays with has a high-dollar 3D printer, and in early discussions, said he could feasibly make me a reduced size butt plate, much like an original one----but then again, there is that pesky legality thing. If I reproduce a 7/8 scale lookalike, am I infringing on anything?

    I think the patents ran out about 100 years ago. “Browning” is a trademark though, and those don’t expire. But even there, I don’t think a one of a kind, personal gun would make a difference.

    You can make anything you want, selling would be a big no no unless you get a license, getting caught with it may be another. I have no doubt in your skills, you can pretty much do anything with enough money. The problem I see with a 410 is there won’t be enough recoil to cycle it. 1/2 ounce or 11/16 ounce isn’t much. To be a true A5 it will have to be a long recoil. And I must say I had some serious doubt about a 28 gauge, until I bought one. Now I love it. I think a 28 gauge long recoil would be easier then a 410.

    Damn just watched a video on one in 28 gauge. Now I want one. Just bought a cxs in 20 gauge last night. Thought I was done for awhile. Who brought this up anyway? Rudolph31 shame on you.

    The barrel will be considerably lighter, as would be the recoil spring, so.........

    I suggested the Franchi as a starting point. I didn’t know I was going to inflame you addicts.

    By the way, since you guys are going to be owning them, it’s pronounced FRANKIE.
