I need an adaptor that will attach a pic rail to another pic rail. Kinda like a riser but with clamps top and bottom.
So does this exist? |

wtf..! That is awesome! |

I'm guessing that thing fires 2 shots, one from the bottom rifle and one from the top, every trigger pull? Definitely wild! |

I cant understand how pulling the trigger on the bottom lower fires the top lower as well. I see that the gas tubes are criss crossed to allow the bottom lower to operate the top lower bolt carrier but i dont see how the top firearm actally fires a bullet. |

Holy thread hijack Batman! |

Brownell's has a modular Picatinny rail system. It doesn't have clamps top and bottom, but has screws that let you vary the height and the MOA offset:

Not mine, but I'm guessing the top is rigged up in full auto with the trigger held back. This will cause the two actions to fire alternately, so you don't get 2x the rate of fire, but you do get a much longer shot string and somewhat cooler barrels.
The reason for the crossed gas tubes is so that firing the lower will work the action on the upper, which because it's wired in the fun position will cause it to fire, which then works the lower, ejecting and chambering a new round, and firing it as long as the trigger is still pulled. Releasing the trigger won't stop the upper from firing one more shot, but this shot will cycle the lower reloading it. Since the trigger is now released it won't fire so the upper is left with its empty shell still chambered, which will be ejected the next time the lower is fired. |

HOLY GUACAMOLE I WANT 2!
Edit: I was tempted to ask how you aim the thing, but does it really matter? Edit 2: A sturdy drop-in bottom-half-of-a-quad-rail-handguard would allow a laser aimer on the top rifle. Accurate mow-em-down shoot-from-the-hip firing, Arnie style.
