MATRIX

This is an enhanced version of our highly successful BA Chassis System.

The Matrix Chassis was designed as the most revolutionary chassis ever produced. With the multitude of configurations in grips, thumb rests and trigger finger supports, the primary interface between the shooter and the rifle (the grip) has over 100 different options. Please refer to the photos above to see our data on shooter preference on the grips, thumb rests, and trigger finger supports.

We have developed a hand measurement chart to identify which grip configuration may work best for each individual client.

Additionally, the location of the shooter's hand, closer to the bore of the rifle, provides even more variation in how the shooter can set up this chassis.
