barrel droop?

I've heard this term a few times, especially about some gamos, but I have a very vague idea about what it is. Can anyone explain to me what it is, how it happens, and how you can tell if your rifle suffers from it? Are there certain rifles that are prone to having it, and is a rifle made with barrel droop or is it something that is developed? or both?

Barrel droop is when the barrel of the gun is not in line with the action. You might be able to see it when sighting down along the side of the gun. It's a problem when you can't get a scope to work properly - the gun tends to shoot low, and there's not enough elevation adjustment in the scope to bring the shot to where it should be. Or you have to crank the elevation almost all the way at medium ranges.

Barrel droop is a factory defect. It would take a heckuva mechanical failure to result in droop simply from use or from wear.

My TF89 had the opposite problem so I had to stop shooting those little blue pellets. Couldn't resist!

My $99 Gamo 440 came with enough barrel droop that a scope could not be used without a adjustable mount. However on Charlie's site there is a tip on how to make a tool to cure droop. It's easy to do and works. Just make sure you can secure the rifle securely in the vertical and adjust in small increments.
