With the new HS403GL, Holosun has updated the design of the successful HS403G.  As before, the battery is housed in a low profile compartment.  The elevation and windage turrets are now low profile like the other sights in the Holosun line.  This provides very little obstruction when aiming, especially with both eyes open.  The mount is fully compatible industry standard mounts including aftermarket mounts.
