DISCLAIMER: ANVL UKON mounts are an emergency backup iron sight system. These were designed as a military requirement to fulfill the backup iron sight requirement while keeping rail space open for the operator. The intended use is within fifty yards or much less in a CQB capacity; if the end users Red Dot sight is damaged battery has died or never powered on. This optic Mount system relies on true mechanical zero between the optic Mount Rail and Barrel to have accurate windage. ANVL UKON mounts are built and constructed to be a perfect mechanical zero from mount to rail. Make sure that your optic is seated correctly and tighten down on the truest mechanical zero you can get. When mounting the optic Mount make sure the amount is completely seated and the picatinny rail is tight against the non screw head side of the rail before tightening. Reasons for windage to be off: Loose tolerances picatinny rail out of spec tolerances picatinny rail non-con Centric Barrel mounting the optic mount to a polymer picatinny rail riveted to a sheet metal dust cover poor tolerancing between barrel and picatinny rail.
