I have 8 of them on various rifles, pretty much shows how I feel about them. No problems from recoil or falling on them and sliding down mountainsides either. Heaviest recoiling rifles I have them on are 338 Federal, 7mm RM and Savage ML. I look for a scope mount that has minimum weight, minimum joints and screws. I have used them for hunting for 2 years now. They have survived the ATV, mountains and all that goes on with a hunting rifle.
