With the CAR system, recoil is reduced greatly. This reduction is achieved through the use of either of two main stances, and by "locking" the muscles and bones of the arms which is accomplished by slightly canting the gun hand.
The canting movement, though slight, greatly enhances stability by changing the alignment and relationship of the muscles and bones in the gun hand arm.
