I installed this on my Savage 111 7mm Mag. I wanted something to raise my cheek weld and store some extra ammo and other small items that I use regularly on hunts. I.E. calls, lens cloth, ear plugs. I love how everything is fully adjustable to make it fit perfect to the gun. I was able to make it tight in the perfect position. After close to 100 rounds it has not budged. Overall very impressed.
