Some times ago we showed a video about a double 1911 gun from Arsenal Firearms, and this is potentially the nearest we will ever get to the same thing on the AR-15 stage.
Shown here by Tony Rumore of Tromix, this “Siamese 223” can deal with a mag dump like no other.
“The most recent and most crazy creation by Tromix is this Siamese 223 for LAW Enforcement just,” expresses the Tromix site.
“The synergistic trade of gas tubes compels the growing gasses from the lower rifle to the top rifle permitting it to cycle a cartridge into the top break then discharge when the bolt is shut.
The gas from the top rifle is then sent down to the lower rifle where the primary unfilled round gets launched out and another cartridge is stacked into the rupture.”
