What is CTX™?
CTX™ stands for Coordinated Thermal eXpansion. This novel technology improves long-range rifle system accuracy nearly ten-fold in environments with changing temperatures.
Until now, long-range rifle systems have been assembled using receivers made from stainless steel, scope mounts made from aluminum alloys, and stocks made from composites, synthetics, or wood. Materials have a specific property to them called the Coefficient of Thermal Expansion (CTE). What this means is that when materials get hot or cold they either grow or shrink in size. If you’ve ever put a bottle of water in the freezer you’ve seen ice expand. While water is the opposite of most materials, you get the idea. Each material grows and shrinks at a rate specific to that material.
Since components are rigidly connected with bolts or screws but expand at different rates, the system deforms. What does this mean for your rifle system? When you have a stainless steel receiver bolted to an aluminum chassis, they will expand at different rates. This difference causes your receiver to bend. This bend in the receiver changes the endpoint of your barrel. While this change may be very small at the barrel, it translates to a massive change the further away from the barrel tip you move (1 mile shot). While the long-range rifle system may still be capable of shooting small groups, proximity to the target is lost.
“it’s a great chassis. Period. Shooting it was awesome!”
