First it was the double-barreled 1911

Now someone has done the same thing with an AR-15:

I wonder how closely regulated the barrels are. If they share a single set of sights, there has to be a single range at which the two trajectories cross, and beyond that they have to spread farther and farther apart. (Unless, of course, they immediately begin to diverge, in which case there's no distance at which both hit the same point-of-aim)

Well, they've got double-barreled shotguns now, so POA=POI is not so significant there.

I had a side-mounted laser on a rifle (which would give the same parallax problem), so I just zeroed it about two inches to the left of POA.  That way the error (which was admittedly small anyway) would stay the same disunirregardless of range.  FYI this was a BSA laser sight on an M4gery I was just trying out.  Got rid of the gun and sights recently anyhow.

It's a novelty weapon.  Accuracy is an afterthought.

[Frank Castle]

Will a bump-stock work on it ?

I wonder what the heck that thing weighs.

Ya know, I've heard of double-barreled shotguns. What'll these kids think of next, eh?

'Course, a 12-gauge tends to be a mite less accuracy critical than a .223.

Somebody make a left eject saiga 12. I have a right eject and a welder.

About twice what an AR weighs if I had to guess

I'm waiting for a tri-barrel rifle where one is a tube-fed lever-action, the second is a box-fed pump-action and the last a belt-fed bolt-action.

No break-action? No revolver action?

I assume the two sides are different calibers. Maybe even 308 and 5.56. So you don't have to decide. And ammo compatibility after SHTF.

Two calibers and one set of sights?  That's brilliant.

It probably doesn't have sights. Everyone uses aimbots nowadays anyway.

What the OP posted does not have anywhere near the class as an H&H though.

[KD5NRH]

I assume the two sides are different calibers.

.22LR and 7.62x54R, so you can find ammo anywhere.

[wmenorr67]

Wonder what happens with misfeeds/jams.

General:

I point out that the article's "drilling" is only an Americanization of the the German "dreiling," meaning three calibers or barrels as in the German counting system:  Einz, zwei, drei, vier, fünf  =  One, two, three, four, five...

Somebody ought to go in there and edit that.

Multi-barreled or chambered firearms are nothing new.  There seems to be a subculture of fascination with them beyond the double-barreld shotgun and the African Dangerous Game double rifles.

well, you can do really fast double taps with it.

I now has two multi barrel guns. 12ga/.222 over/under and a 16x16-9.3x72 drilling. Both slightly more classy than this. Someday I get the 12ga .30-06 drilling, just hopefully not soon.

Working your way up to the 4-gauge, .50 BMG model?

Working your way up to the 4-guage, .50 BMG model?

That would be awesome!!

Local pawn shop used to have one that I really wanted as a SHTF food getter; 20ga/.22Hornet.  Pound for pound, squirrels, rabbits, turkey, quail and dove are likely to be more of a hunter-gatherer diet than deer, and 20ga means fewer pellets to pick out of the meat, while having the .22Hornet means you can easily take a whitetail, feral hog or stray cow target of opportunity without having to switch guns.

Gauge is spelled with the a before the u, as in a,e,i,o,u, that is, alphabetically.

Not being a jerk, but that's a pretty common spelling error.

If in doubt, use ga. or gage, which is an acceptable alternate spelling.

Odd that the Firefox spell-checker didn't catch it.
