Our teams employed the L3 511 for the POTUS visit nearly two years ago and have had nothing but problems with this sight on their 7.62 HKs.

Mounted and zerod and after a few rounds, seemed as if the original zerod sight was outta whack by a degree or so. Additionally, the two AA batteries would die in spite of the auto off feature when stored with the sight mounted and batteries installed.

The sights were shipped back under warranty and the QC department could not replicate the problems other than issues with illumination.

Any hints, war stories, etc most welcome as our sights come back shortly.

Thanks in advance, Stan
