HOLOSUN HS403GL Red Dot Sight, 50,000 hours, parallax free, PEO/MAO finish, and limited lifetime warranty. With the new HS403GL, we have used the design of the successful HS403A, but we moved the battery housing to the right side of the optic. This provides easy access to change the battery. The compact battery housing has a lower profile than the windage turret. The mount is now fully T1 compatible. You can use any aftermarket T1/H1 mount for this sight. The turret adjustment mechanism has been updated with it being 3mm higher than the HS403A, to make it easier to adjust with a gloved hand. All other features are identical to the HS403A.
