Would you rather carry ammo and have to load it, costing you valuable time, or would you prefer it in your gun?
Of course the answer is always “in my gun.”
Of course the answer is always “in my gun.”


Roth Concept Innovations, LLC ("RCI") is the ONLY manufacturer of the XRAIL Systems: add-on shotgun accessories that are versatile enough to use one unit on more than one shotgun, giving capacity up to 23 rounds, and does not alter the original gun. From military and law enforcement to competitive shooting, if you need extra rounds in your shotgun (for less than lethal such as crowd control or to shave time off your score in a competition match), the XRAIL System is the solution.
Our Mission: To provide the best high capacity solution for your shotgun that is easy to use, durable, and installs in minutes.
What it is: XRAIL Systems are Xtreme Roth Auto Indexing Loaders for shotguns. It is a magazine extension system for shotguns that will allow a shotgun to have extra usable rounds of ammunition. An XRAIL System loads the same way you would normally load your gun. Once the main tube is full, you rotate the XRAIL System to the next auxiliary tube and load. You repeat until all tubes are full. When you shoot, the tubes will automatically rotate back to the main tube as the ammunition is unloaded. The XRAIL System is flexible enough to be “topped off” or if not needed, you do not have to fill the auxiliary tubes and just use the main tube like you would normally use your shotgun.
RCI's Add-On XRAIL Systems:
XRAIL Systems are made of hard coated black anodized aluminum and stainless steel all non corrosive with black nylon or clear polycarbonate unified tubes. Compact unit weight is 1 lbs 8 oz. empty and full version is 2 lbs 1 oz. empty. Weight of units full depends on type of ammunition used. Installation requires no gun smithing and can be done in minutes.
XRAIL Systems are designed to fit multiple shotgun platforms and are very versatile. The XRAIL System purchase comes with the connecting system you choose. To switch from one shotgun platform to another, one only needs to purchase a different XRAIL Connecting System. RCI’s XRAIL Combo System will come with one platform connecting system, one outer housing and both compact and full version inner tube housings which can be switched in less than 2 minutes.

There are various high capacity solutions for the shotgun, but ours is the only one that is NOT a gun (which means you still have the dependability of the gun you are currently using with the benefit of more than doubling its capacity), has the versatility to be used on more than one shotgun, and keeps the gun length shorter than using traditional extension tubes.
XRAIL Systems and all RCI products are 100% Made in USA.
