Remington 1740: My Project Begins.

    I thought I might as well share the beginnings of my 1740 project. I got this idea a long time ago while playing Doom, or Duke Nukem, or one of those horribly cheesy gut-blaster shooting games. I thought to myself, "Could it be possible to have a double barrel pump action gun?"

    Skip ahead a few years and here I am with the guns, the materials, the knowledge, and the great help and support from a great firearm enthusiast out at my church. After purchasing a used right-handed 870 and a new left-handed 870 from Bud's gun shop online, I was ready to start brainstorming.

    I called up my friend and set up a time to head over to his house. After dissasembling each shotgun completely, we both ran through how it could be done. Here's what we're planning on doing.

    For the receivers: Two long pins to replace the four smaller pins. These would go straight through both recievers and trigger mechanisms of each shotgun, providing a main support. For this, I've already found some screw-pieces that fit pefectly in each hole. Once they are cut to fit and tightened, it should be plenty of support.

    The forend of the gun: A tricky part which required both of us to think a little bit. Since we couldn't make any real handguard that went over both ends, we decided to scrap that idea and start again. The plan is to find some thin-walled piping (which I found, but didn't buy because I was still looking around. Kicking myself for it right now) that would fit over the mag tube and into the area between the nut right behind the mag cap and the lower lip that catches the forend. One on each of the mag tubes will be needed. Once we have that, Another church friend of ours (God bless southern baptists) has a mig welder and will weld a piece of 16 gauge steel (which I have) that has been cut to fit between each of the pipes. Once that's done, I can bolt whatever piece of wood I want onto the forend, so it opens up many more possibilities for furniture.

    For the buttstock: This one was my idea, and it probably isn't as ingenious as the rest. Looking at the width of the receivers, a properly sized buttstock that went over both ends of the receivers would allow no room for my finger to reach the triggers (more on the triggers later). He was talking about just putting a skinny normal buttstock between the two receivers, but that just wouldn't look good at all. So I thought about it and came up with this plan: On the left receiver, stick a normal buttstock. On the right reciever, stick a PGO stock that is almost vertical. That way, the left full buttstock can reach my shoulder easily and I can work the shotgun with my hand on the PGO stock. Not pretty, but very servicable and probably the easiest thing we could do. I may stick a piece of steel to replace the rubber butstock on the full stock to balance it out a little better, and that stuck will have to be ground down a bit where the PGO will fit, maybe. We're not quite to that part yet.

    As for the triggers, I'm leaving two triggers, but if I can 't reach both of them in the current setup, we will stick a large trigger shoe on the left-sided trigger to make it easier for my finger to reach.

    I plan to have a couple different barrels for these guns. I want a slug barrel for the left handed receiver, as I could use that as a slug gun, mounting an optic if needed. I can put any barrel combination I want on this gun, and the best part is that if I ever grow tired of it (doubtful), I can easily convert both shotguns back to their original configuration. No permanant changes need to be made to the shotguns.

    Now I have a few pictures of what it looks like right now. Take a look. It's not much, but it may help with visualizations.

    I'm not really sure how practical it'll be, but the concept sure is cool.

    Will do. Next time I'm in town I'll be picking up the piping pieces to go over the mag tube, and with that I can begin work on it again.

    And Practical? Practicality ends where fun begins.

    how will the safeties be used? btw, it is a really cool project:cool::cool:

    FWIW years ago if I remember correcly Soldier Of Fortune magazine had a write up on a double barrel Remington 1100 shotgun I forget what it was called but the concept is the same as what you are trying to build.

    Curios to see how your idea will end up it looks interesting it is something along the lines of one I once thought up using two bottom ejecting Ithaca 37 M&P 8 shot shotguns making it into a bullpup with an Eotech sight in the middle mounted between the barrels.

    Best of luck. :)

    The safeties are one problem that I'm still trying to figure out. Since the controls on each shotgun are opposite, when the safeties are both on "fire" mode, they are pushed to the inside of the two shotguns. On safe, they are both on the outside. I can reach each safety rather easily, so I'm not sure if messing with the safeties would really be needed. I'll most likely take a look at it once the gun is completely made. If it was an Ithaca bottom-ejecting gun, I would simply stick a pin between the two safeties, but I wanted two 870s for their 3" mag ability and the awesome double-side ejection it'll have. (Definantly points for being cool)

    Just about done, just lemme get ahold of a mig welder...

    I've got the forend figured out, and after I get some steel welded up right I'll be ready to put some nice wood on it. However, I need some guidence on the barrels. I accidently ordered two right handed 18" barrels from MidwayUSA, thinking "Hey, they're 870 barrels, I'll go ahead and get them and call it a day!"

    Oops. My bad.

    So now I'm sitting on a bead-sight 18" IC RH barrel for an 870 that I can't use. And not only that, but I'm not finding any 18" LH barrels. I'd love to buy a slug barrel and all, but my car's radiator just went out and I need to shift funds over to pay for that. That doesn't mean my 1740 and my Saiga are taking the backseat, since I already have all the parts needed for both of them.

    For now, though, while I'm doing the final work on the forend and waiting for Midway to send me the right part (they send me the wrong stock the last time I dealt with them), I'll be looking for a place to purchase a LH barrel for an 870.

    anyone have any ideas?

    ...And we're ready for a test!

    Alright, for those five or so people that's been following this, these pictures are for you.

    I've finished the forend extension piece that will be used to mount a wooden forend. However, that forend exists only in theory as of now. So as soon as I fix up something to afix to it, it'll look much, much better. But right now it's ready for a test or two (or three or four or five)! The only fix as of now is the full buttstock on the end needs to be ground down a slight bit around the area where my hand fits onto the pistol grip. There wont be a need to extend the left trigger, as I had originally thought, since I can reach and operate both triggers rather easily in this set-up.

    A few things on this project that I'd like to do in the future:
    -Get an 18.5" LH barrel to match the RH barrel I hae leaning against my wall.
    -Get a LH rifled barrel with a built-in scope mount
    -Heat shields for both short barrels, plus the fabrication of a bayonet mount to use with my Remington 17" bayonet I own. (Purely for aesthetical coolness)
    -Perhaps get a wooden PGO stock so the entire furniture set can match.

    This is going to be one of those projects that I'm going to be working on a for a while, just messing around with and adding onto.

    And for all those 870 purists out there, I went into this project with the intention that, if the project itself blew up in my face, I could put each gun back into its original configuration without any harm done to either gun. Each of these 870s can be put back into their factory-condition anytime I want. Much to the dissatisfaction of my future brother-in-law. I promised he'd get the LH gun, since he is left handed, for a wedding gift if everything fell appart.

    So here are a few pictures. The fabricated part does look a bit ugly right now. I'm going to clean it up a bit one of these days.

    Yeah, a face only a mother can love I guess. But then again I've got weird tastes in firearms. I'm just happy to see it come together.

    I like it. Keep us informed, and if you get to MD with it we'll try some Wobble Flurries.

    Ok so how do you

    I saw this tonight for the first time and:

    My first thought is how do you depress both slide releases at the same time.

    Then do you try to fire both barrels at once or like a two trigger SXS?
  16. Deer Hunter

    Deer Hunter Well-Known Member

    Dave, if I'm ever up that way I'll see what can be done!

    Big Al, it isn't hard to depress both slide releases at the same time and pump the gun. The gun's action is actually very slick. It feels like any-other 870 action that I've used. I had to grind down a bit on the fabricated part to fit a few clearances, but once that was done the pumping smoothed up big time.

    And I left the triggers like they are. Two triggers that I can reach easily. I thought I may have to put a trigger shoe on the left handed trigger to help me reach it, but it doesn't need it. I can manuever my finger to fire either one of them or both at the same time. I didn't want to fire two barrels at once all the time.

    I think it would be more functional if you were able to move both slides independent. This way, you could have one set up with slugs, and wouldn't have to dump shells if you needed a second slug, but didn't want to waste the load in the other shotgun.

    I can't believe that I'm actually thinking of possible uses for this.....

    Have fun with your project, it looks like it is a very fun gun.

    I thought about that, but figuring out a way to pump the actions seperate from eachother was a hassle, not to mention making the guns set out from each other. I wanted the two guns mated as closely to eachother as possible. I'm sure I could have set some kind of locking system on the forend for me to be able to choose which pump I want to operate, if not both at the same time. However, I'd have to brace the mechanism some other way, possibly by binding the two barrels together (not likely) or attatching something to the end of the magazine caps. The way I have it now is the absolute strongest possibly configuration, which is what I really wanted for it. The gun itself is incredibly solid. There is no rattle, wobble, or anything to suggest that it is two guns (other than the blatent obviousness of that fact).

    And I plan on taking this gun hunting with me. It'll take a few ducks, maybe a dove or two. And I'll drag it into the woods with me this fall and hopefully come back with a white-tail. Why not? It throws lead just like any other gun, but looks a lot cooler while doing it! If you guys thought it was fun seeing one smoking hull fly out of your shotgun when you pump it, imagine one from each side of the gun. And recoil is nearly non-existant. I fired both barrels at once of 12 pellet buckshot. It nudged me back, but that was it. It wasn't sharp at all, just a gentle push. And without the noise and flash, you wouldn't be able to tell if the birdshot even went off.

    My dad had a revelation when I let him shoot it. First off, he finally accepts that it is, indeed, an extremely fun gun. Secondly, he had an idea for the forend. Since I'm looking for some wood to go on the forend part, he suggests getting a wooden baseball bat and carving it down to the specifications that I need. Very neat idea, so I'm going to toy with doing that.

    Okay, I just found this thread.

    That is AWESOME! :D

    Seriously, I don't know what I would do with one, but I want to build one now.

    If you haven't solved the safety issue, would a cammed lever system work? You could attach levers to the inner (the side facing the center of the joined shotgun) and have those levers cammed to a central lever running up and between the actions. For example, pushing the central lever forward would cause the levers would move the safeties into the off position by pulling them to the interior.
