It is worth noting that Bix’n Andy triggers are very easy to disassemble and doing so does not void the warranty. Below is a labeled picture of a loaded Bix’n Andy with green arrows to show the direction parts move when fired and blue arrows for labels. They tried to explain this in their product literature, but I didn’t really get exactly how it worked until I took the thing apart, analyzed it, and compared it to other designs. The idea is that the ball bearings can move with less friction than a pin could, allowing your trigger to be smoother, more consistent, and have a lower topsear force. Bix’n Andy’s big idea is to get around using a pin that rotates under great force by having two ball bearings bear the force at this key place in the trigger design.

It can also result in partially pulled triggers not resetting to full sear engagement and a high necessary reset force on the topsear which slows the lock time and causes drag between the firing pin and bolt body. This often adds weight, and therefore friction, to key pivot points, which can result in things not feeling so smooth. One great problem encountered in the design of these complex triggers is that taking more weight off the sear means that it must go somewhere else. Things get more precise, more expensive, and, usually, more prone to fail when dirty. The added parts tend to add greater adjustment, lower the weight on the sear surface, lower sear engagement, and also lower pull force. More expensive, lighter pull weight, and more complex triggers tend to add more moving parts and levers to this. The Walker diagram above is a good example of this simple design and one of the best loved executions of such. Most triggers are very simple having one sear edge on the trigger and the other on the topsear that interfaces with the cocking piece in the rifle.

#BIX N ANDY PRO#
Throughout the review I was able to test a total of four different Bix’n Andy triggers, which included a TacSport, the TacSport Pro in both single stage and two stage configurations, and a prototype TacSport Pro that featured a little different spring configuration. This was in response to some of the PRS guys wanting a lighter pull weight but not wanting to use the benchrest model because those are too susceptible to dusty conditions. The TacSport Pro lowered the weight of the TacSport from a 10oz – 4.5lbs range to a 3.5oz – 2.2lbs range.
I had the card of the Bix’n Andy importer Bullet Central from some year at SHOT Show, so I gave them a call and they told me they had a new TacSport Pro model coming that they were interested in me trying out. This made a particular impression on me since not that long ago, Kelbly’s had actually manufactured high performing, exceptionally low pull weight triggers themselves.
The last straw was when I saw that Kelbly’s had decided to make Bix’n Andy the standard trigger on all their rifles. I kept hearing that it didn’t just work differently but actually WORKED differently (you can figure that one out). I couldn’t escape talk of this Austrian made Bix’n Andy trigger with balls. It is just that a lot of companies make triggers that work well enough, or, at least I thought that was the case until recently. Normally, I really don’t spend much time thinking about triggers.
It is now to the point that this is clearly a review on its own and not a sub-section of another. However, I became more interested in the intricacies of the ball trigger concept, and the text kept growing. Initially, this was intended to be a sub-section of the Kelbly Atlas Tactical custom rifle review.
