    Good for you.

    Just don't EVER produce them for anything other than your own use, don't sell them, make them for your friends, or publicize your drum in print or on the internet if you are successful.

    It's not illegal for you to do, assuming you live in a free state, but if the ATF-sometimes-E gets wind of these in circuation, the Saiga 12 is going to the Secretary of the Treasury with a request that he or she classify the Saiga 12 as a Destructive device, like the Streetsweeper, or the (even semi-auto) USAS 12.

    Then, it's "amnesty" time and $200 for everyone who already owns one, then no more for anybody else.

    My father designed allot of innovative artillery and machine guns, but the ones that really made the money were the M52, M110, and M107.

    When I was a little boy, I thought that red hydraulic fluid on the ground was blood from shooting people with these guns.

    I've got a couple of pretty good designs floating around in my head. Some are just 'actions' and some are complete firearms. I'm waiting to get further along with my ME degree before I really flesh 'em out and polish 'em up. Two of them I'm reasonably sure I'm going to pursue patents for.


    EDIT: HAHAHAHA!!! I just realized I posted basically the same thing in this thread 2 years ago! :D

    Well I've had a few ideas bevfore but never realy built anything. Not got the machine tools, skills or paperwork required! :D

    Like to build a (non-firing) replica of the rifle used in Day of the Jackel film though...

    I drew one up one day when I was in class bored out of my mind, it actually fired spider monkeys and was meant to fight zombies...it was totally cool.

    Yes, I have some interesting designs. Sorry, but I am not going to elaborate. I will say however, that someday I want to build a motorized minigun! Don't even know if it's legal, but I want one.
    Edit: Of course, I won't be breaking any laws.

    Miniguns are already motorized.

    Yeah, I realize that, but I have never built one. The mini gun I wasn't claiming as my own idea, just something cool. :D

    I'm always drawing up design ideas I have for firearms. Aesthetically, I'm big on futuristic styling and flowing curves a la Cx4, Rx4, F2000, etc. I'm constantly trying to think of innovative internal mechanics, and haven't really come up with anything groundbreaking yet... although there are a couple concepts I might pursue at some point.

    I always thought a belt fed 12 gauge would be cool but couldn't figure out how the mechanism would work.

    Since I inlisted in the crotch, I was issued an M1. When they replaced them with the POS that jambed all the time I've wanted my M1 back. I sure can't afford the ones they have for sale (bunch of thieves), so I'm buying the part one piece at a time and building my own damn M1. I got about half of it now. Once I get it that done. I'm starting on the one I carried through ITR, the BAR. BTW never ever hit the TI, even if he hits you first.

    Not exactly designed but built my own

    I decided to build my own 45 match pistol from a mis-mosh of spare parts and a Caspian frame and oversized slide.

    After reading a number of publications on how to do it, I figured I had the tools and the b***s to try it myself.

    The toughest part was honing and filing some expensive parts the last thousandths of an inch or so to meet the perfect machine fit.

    It took about 2 weeks or so and the results were outstanding.

    The gun shoots less than a 2" ten shot group from a Ransom Rest at 50 yards.

    Here is a picture of the gun and a target I shot freehand.

    To heck with my own design. I want the one from The Cat Who Can Walk Through Walls by Heinlein, it fires a 4mm dart that explodes when it gets inside the body. Now thats stopping power!

    I've only ever had ideas that are either Sci-Fi only stuff (like the V-ACT Weapon System or the Smart-Scope) or just plain stupid (like the AR-440 or the 12-gauge RSS).

    If anyone fancies a laugh, I'll post them.

    Somehow I don't think my water-pick powered squirt gun would qualify. My mothers husband help me to put it together when I was about 12 or 13. Even worked out a portable power source using NiCad batteries from old R/C cars I had. Fully automatic and would put a nice sting on you if I caught you up close. I still might have the thing in my mothers attic.

    Designed? No. Built? Yes . . . Discussed here: 1911 LW Commander gallery

    Built by me working with Jim Garthwaite during a week long "Build your own 1911" class. All parts came unfinished and oversized.

    Most of mine aren't even to the design phase yet. They're set up in a story on the borders of going from today, to sci-fi. The first was the idea of using porting and such along with heavy recoils systems to make not a "recoilless" gun, but a "managed recoil weapon system"(complete with fancy military name). A balance between a traditional recoil system and a recoilless gun that uses a smaller cartridge(more ammo capacity and efficient powder use) but lower recoil. It was intended for weapons for first generation power armor and mecha--full power shot, but recoil managed to the point where the lighter firing points could handle it. Then I saw a video of that "high impulse weapon". Similar idea, though since I was going with armor, I wasn't concerned with low blast effects, just cartridge size and recoil.

    More recently, I was looking at rail guns(high round count guns), I just need to find someone to talk about patents with. It's possible that the idea is already out there, just classified so I can't find it on Google. More recently, my dad found a fusion reactor design that makes ball lightning, I think it'd be fun to shoot that out of the rail gun.

    There's also intermediate guns for power armor. An M240 designed to be fired one-handed like a pistol, and a modified M2HB. This would be modified to feed off a 20-30 round magazine put in a modified top cover. I didn't think a large magazine on your back with a chute going to the gun would be reasonable, and dealing with loading a belt with large, powered gauntlets I figured would be out of the question too. So, you'd double stack magazines to stick in like a normal gun.

    I had a few other ideas, like the M2 above would have the mag release set up so that when the last round is chambered, the follower hits the switch to release the mag, and you load another. That way you don't have to worry about a holdback, or charging the gun. Thinking about a normal rifle, A story about Hammer's Slammers had a gun that had a paddle that blocked your sights when the magazine was empty. It might be useful, but a bit complicated, and would have to be designed so that if it breaks, the sights are still open, and it doesn't jam the mechanism.

    Funny you should ask....I've come up with what should be a practical air powered (actually argon or helium from a 3000psi tank) Gatling gun. Using old Mosin-Nagant barrels, 00 buck projectiles and the aformentioned high pressure gas. And each barrel could fire multiple times per revolution (e.g. on a six barrelled gun 3 barrels would fire similtaneously. x3 firing cycles per revolution.) Not as complicated as its sounds, although I'm sure I'd find some complications when I actually built it (suspect reliable feeding at high revolutions might be a problem). Obviously not real portable, but wicked rate of fire.

    But, I lack the machine tools required (but not the knowledge to run 'em) so it's just stuck in my head for the moment. Maybe someday........

    I have the blueprints for a Brass / Wood Cannon, I just have not got to it yet!

    I have made some potato cannons with calcium carbide..they are neat!

    But I have done some cartridge work myself... I did a .41 Magnum Accelerator for a Thompson Contender. I machined Teflon Sabots for .41 Caliber to accept a .30 cal Nosler Partiton Balistic Tip. It was very hard hitting from a contender 14" Barrell with a Compressed Load.

    Disclamer: Do NOT TRY THIS AT HOME.. I relinquish myself from any and all liability concerning this wildcat cartridge.:) You are on your own!!

    Designed... no... ideas yes... decided what i wanted, put it together, blueprinted, made it run all that happy jazz... yes.... results are better than i could have hoped for... Some day I'll whittle out or find a "fancier" stock for it... til then it'll just continue to put big game in the freezer :)
