Holosun HS403G Red Dot

The HS403G Red Dot Sight shooting scope allows for 50,000 hours, parallax-free use and has PEO/MAO finish, and limited lifetime warranty. With the new HS403G shooting scope, we have used the design of the successful HS403A night vision optic, 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 of this shooting scope has a lower profile than the windage turret. The shooting scope mount is now fully T1 compatible and 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 shooting scope.
