The RCI XRAIL (Roth Auto Index Loader) is a auto index loader magazine extension that can expand a tubular shotgun magazine to hold up either 14 rounds (compact version) or 23 rounds (full version).

This video shows the XRAIL mounted on a Benelli M2 Tactical. The benelli magazine appears to be shortened and the gun can now hold a total of 26 rounds.

Now I will be honest with y’all, I don’t actually know what an “auto index loader” is. This is how I imagine the system may work:

* Each of those tubes are a magazine.
* Each of those magazines feeds into the shotgun magazine.
* Once a magazine is depleted it rotates.
* The final magazine contains a spring long enough to feed the shells that are in the shotgun’s magazine.

Because I enjoy making you suffer by awful drawings, here is a graphical representation. The blue box represents the shotgun magazine. The red boxes represents the XRAIL magazines. In this example the shotgun magazine holds three rounds while the XRAIL has three “magazines”, with two holding two shells, and the third a spring.

First two shots


3rd and 4th shot.


Last three shots

I have watched the above video frame by frame and there is seems to be some additional things happening during the magazine rotation. Maybe I am completely wrong … in which case I would have patented my above idea and not blogged about it

The system will be able to work on multiple guns. From what I have seen on youtube Benelli and Remington autoloaders work with the XRAIL. I don’t see why this system could not be adapted to work on pump action shotguns, aside from the fact that if would have to be mounted quite far forward.

A very interesting product. Hopefully it will come to market soon (and probably a video game as well, when game designers get word of it)

The U.S. Army and Special Operations Command are stepping up efforts to procure a lighter, modernized .50-caliber machine gun more easily transported than the standard 85-pound M2.

The goal is not to replace the M2, a combat fixture for 70 years, but to augment the inventory with a .50-caliber weapon that brings the same firepower at less than half the weight, Army officials said here at the Feb. 27-29 winter convention of the Association of the U.S. Army. Early models of the Light Weight .50-caliber (LW50) are expected to be delivered this year.

This video is great! It shows a Japanese katana sword being shot at by an M2. See what .50 caliber FMJ bullets do to a steel sword!

I am very surprised it lasted even one .50 BMG round!!!
