When hunting in the West most of us take both a tri-pod for our optics and shooting sticks into the field. The Primos Lift & Lock allows you to use your tri-pod or any other rigid shaft and turn it into a secure solid rifle rest. The Lift & Lock is made from rubber coated aluminum: it will not scratch your gun or tripod. It is light weight and it sets up in seconds. Simply attach it to one of your tri-pod legs and have you a rock solid gun rest. The Lift & Lock works on most tri pods and shooting sticks.
