This is a nice sight. It has two positions for zeroing. I personnaly use the lowest position.
Mount is solid.
ISSUE - There is a an area of weakness however. In the middle of the sight where the position lever holds the aiming sight the alloy is too narrow. This is by design because of the spring on the mount. If you accidentally catch the sight on an object it bends very easily and snaps easily. The alloy is too soft and too narrow, I found this also with some of the APS other parts that alloy is a bit on the soft side and it snaps too easily.
