Here’s a radical new rifle. Instead of a vertical trigger that moves rearward when pulled by the index finger, this Blackwater T.O.R. A1 rifle has a lever INSIDE the lower receiver. That lever is moved by the operator’s THUMB, causing the rifle to fire. The claimed benefits of the “thumb-gun” are: 1) Improved Ergonomics (thumb stays in alignment with point of aim); 2) Better Mechanics (thumb is strongest digit and can manipulate lever easily); 3) Enhanced Safety (trigger blade/lever is not exposed).

This AR-type rifle was developed by Iron Horse, now partnered with Blackwater Worldwide. The new T.O.R. (aka “Thumb Operated Receiver”) A1 is the industry’s first AR-platform rifle incorporating patent-pending, lever-driven fire technology.

Iron Horse A1 Precision Rifle
The manufacturer has made some interesting claims about this new thumb-lever system. Blackwater/Iron Horse claims that “Multiple samples of users show a shorter learning curve and reduced shot group size”, and that the design “lends to greater accuracy in precision shooting… with its inherent natural ergonomics.” One claim we do believe, is that the thumb lever may help disabled shooters. Additionally the manufacturer notes that because the “trigger guard completely encases the trigger” there is less chance of snagging the trigger in brush or vegetation.

How the Lever Trigger Works
The operator’s thumb goes into a port in the top of the polymer grip (see grip photo above). This allows ambidextrous firing by right- or left-handed shooters. The thumb points forward, in line with the barrel. The lever itself is contained INSIDE the lower. Watch this video to see how it works:

Is the Thumb Lever a Game-Changer?
“Ironhorse’s revolutionary trigger system has the potential to be a game changer” states Eric Prince, Founder of Blackwater Worldwide. “Our in-house testing has shown a significant decrease in shot group size when compared to a traditional AR-15 trigger set. We think this technology … could replace traditional triggers altogether at some point.” The manufacturer states that the thumb-operated trigger “has been shown to greatly enhance the experience of a large portion of the shooting community and makes shooting possible for those who have limited mobility or severely injured fingers.”

About Iron Horse and Blackwater Worldwide
Iron Horse Firearms, based in Salt Lake City, Utah, was founded by a former U.S. Marine Ryan McDonald. The Patent-Pending Thumb-Operated Receiver was first developed in August of 2016 and became a fully operational system in the fall of 2018. Moving forward, Iron Horse Firearms will be doing business as part of Blackwater Worldwide.

In 2019, Blackwater Worldwide re-entered the firearms and ammunition market in the United States. In its first year of operation, it has acquired or developed multiple firearms lines and a proprietary ammunition line. The company is headquartered in Concord, NC.
