The Caldwell® StingerTM Shooting Rest combines an innovative design, ultimate user functionality and rock-solid stability. An integral feature is its front elevation system that uses a spring-loaded height adjustment knob for fast, one-handed coarse elevation adjustment. Molded front and rear supports protect the gun's finish and provide firmness for rock-solid shots. Front rest easily slides forward or backward to desired length, then locks in place using the quick cam locks.
