I'ts been almost 2 months now since i've mailed RFJ.. havent received a response yet.. as i understand they're buried in work... so... i thought id ask ATS.. i'm wanting an over/under .556/.223 over and an under of 12 g, on an AR type platform, with an option of changing uppers, to maybe .308, maybe .50 beowolf, maybe .50 cal..

A basic layout of my weapon desired..

1. AR platform
2. Over/Under 556/223 on top , 12 g under, with ability to change uppers..
3. Quad railed for multiple acessorries as i choose. optics/lights, NV, laser, bi pod
4. A single trigger mech, with a "switch/lever" on the side to distuinguish what barrel to fire..
5. both 556/223 and 12g semi-auto, with 556 being mag fed, & 12g being tube fed, as i wouldent want 2 mags hanging out the bottom...


My questions are...

is this even possible, with the single triger mech, and how would a tube fed semi auto work?

would the release of a 12g round ( magnum buck shot ) effect the optics of the precise 556?

would it be to heavy?... ima strong man so... but still carrying this would be much better than 2 weapons... ?

any ideas/comments/complaints/adjustments would be most appreciated ... thanks..

I don't know if it's possible or not, but that is now my new dream gun.

Yes this is very much possible and relatively easy to do. All you need is a Bridgeport mill/lathe and some material, (titanium, chromoly, aluminum) depending on what part you are making, and some guns for parts. Oh yeah maybe a couple weeks of free time.

2nd to say I want to shoot it.

3rd to say; call those "Sons of Guns" dudes...

Promise to come back and post or u2u me with a pic if you get it made?

peace

Sounds like an AR with a Master Key short barreled shot gun mounted underneath. They are pumps. not semi.

You need to go and talk to a class 3 dealer in your state before you get your hopes up.

Depends on your state. If they say yes you have a $200 federal tax stamp to buy.Paperwork. You can never sell it only transfer it. Its a lot of hassle for not much benefit. Paperwork and tax stamp can take months.


If I was going to do something under an AR it would be 37mm and parachute flares. no paperwork and you can launch as may flares and smoke canisters as you can afford. Turn night into day. Now that is a real benefit.

Yea you say custom built your gonna have to actually make the pieces yourself. if i understand right you thinking about 2 'main' barrels dif caliber? then a underbarrel shotgun? sounds like some future # op but can probably be done, but 1 thing i think u would need seperate triggers 2 for dif calibers then the one on the shotty ill try n draw how i kinda visualized what u said. tell me what u think


see u got the two barrels dif clips for each near the back two triggers bottom 1 would jave to be worked on scope shotty near front trigger for it.

I got it...the mother of all guns...The AR-15/12ga/BAZOOKA !!

to do it as a single trigger would be difficult if not impossible without switching over to Electronic triggers for both weapons....

Now as far as I know electronic triggers are legal and it could be done this way.

Now onto your tube fed semi auto shotgun. There are literally dozens of choices of off the shelf tube magazine fed semi auto shotguns which can be modified to fit under the barrel of your AR platform. Just so you know red jacket already makes a pump action shotgun and AR 15 combination gun. On that gun though you have a separate trigger for the 12 gauge.

All in all I'd say your idea is doable but will cost a pretty penny and you are talking about adding a lot of complexity to get two guns firing off of one trigger. I wish you luck and please do post if you do get it built.
