12 Gauge, AR-10 Based Shotgun Now a Reality
If you want a high capacity, semi-automatic tactical shotgun feeding from a box magazine, the Saiga-12 is pretty much your only option. Ho hum. But wait, a challenger appears!
Intrepid Tactical Solutions is releasing the AR-12, a 12-gauge shotgun upper that fits on standard SR-25/PMAG type AR-10 lowers. The upper is piston driven. The user must install a stouter, shotgun-specification recoil spring in the buffer tube, but otherwise the lower half of the gun remains the same as an AR-10. An 8-round single stack magazine has been designed to fit in the big AR-10 magazine well.

But wait, there's more......
The genius of the AR-12 may also be its downfall — proprietary ammunition. Traditional 12 gauge ammo doesn’t get along well with box magazines due to the rims of each round stacking up against each other, and there are other complications as well. Ask Saiga-12 owners and they will tell you about the long, hard road to getting one of those guns to work reliably with cheap, low-brass ammunition. Intrepid went outside the box and designed a new, all-polymer 12 gauge round that resembles a scaled-down 40mm grenade, with a rebated rim, round nose cone, and “payload” area containing the shot. This new RAS-12 ammo is said to be key to the AR-12′s reliability and terminal ballistic performance.

Saw an MKA 1919 in the LGS today $1000 and it takes standard 12 ga.

Unless it works on standard ammo its just not worth it. Fwiw, i don't really see a need for a box type mag on a shot gun. Yeah its cool and all, but is it really that usefull? Last time i checked a mag tube reloader is faster then a mag change. there was also a company that mad a rotating mag tube deal( not sure if they ever got it too work or it got canned by the atf)
-
Didn't I see a thread on here in the last few months about a new type of shotgun ammo?
Gee, who could have it been that started that thread? ;D ;D ;D
I guess they should have checked here before they went down that road...
-
We would have told them the same thing we told you.
It's a non starter. ;D

Having seen their solution I hope it catches on but as per our previous discussion I don't think it will. ;)

That's the XRail mag.
Spring tension would rotate the shells around and give the shooter 22 rounds to use.
Downside is it's HEAVY AS HELL and expen$ive - $650.
I wonder if MB has two. ;)

20 rounds in a drum magazine will be heavy, but put that same 20 out near the muzzle and you got a challenge shooting trap or skeet.

Jerry Miculick (sp?) shoots it, and he has no problem with the weight. However, it is a full box of shells hanging out there, and he is better than anyone I've seen all around with three gun.

Jerry has no trouble with lots of things normal humans struggle with ;D ;D ;D

And here I ask ...Why? If you can't get it done with 9 rounds of 00, are 11 more going to help you? The way I look at it, the shotty is for home defense. I doubt you'll fire more than four rounds before it's over one way or another. If I need to go beyond that I'll pick up the AR. No mag issues or strange ammo required, just 30 rounds downrange. Just my .02.

The first answer that pops into my head is that 12 Ga gives you more options such as tear gas, bean bags, slugs, buckshot, etc.
-
More ammunition allows the weapon to handle more situations than personal self defense.
Without to much fanciful imaginings, we can envision riots, gangs, looters and flash mobs.
Some folks will be considering the need to use their weapons for "homestead" or neighborhood defense in survival scenarios.
If you plan for any of that, having a shotgun, or any other weapon, able to deal with it along with personal self defense is the goal.
-
Those that have exchanged fire never complain about having too much ammunition. ;D
-
Looks like I misunderstood FQ's question, I thought he meant why 12 ga rather than 9mm or some other caliber.
Why bunches of 12 when you could use smaller ?
Some people think "bigger is better" ?

Because many stages are set up to require 15 - 20 shots, and reloading shotguns on the run is a pain.

I went back to the OP, Then I looked at the MKA 1919

And saw another reason.
With this, you can have a 22 plinker, a 5.56 carbine, a .308 precision rifle, and a 12 Ga shotgun all with the same action and the same controls located in the same places .
Train on one the .22, shoot and maintain all of them.

oh H*ll Tom that makes too much sense, we can't do something like that ;D
