BCAR Crush Levels - Project-Stinger/Main GitHub Wiki
Crush levels are indicated with a number on the back of the BCAR. A higher number means a higher crush. For production units these are 3.0 and 2.7 for high crush and low crush respectively.
This number originates from the following dimension, and can be tuned in the future, which is why I display the number instead of just high or low crush.
It is the distance from the outside circle of the BCAR.
