Madhouse Design's Dual Sight System elevates the AR-15 from effective to absolutely lethal. By allowing you to mount both your close range sights (battle sights, red dot or reflex sight) and your scope simultaneously, you are able to "stay in the zone" by targeting close, medium and long-range targets quickly, with great accuracy and with no adjustments. By sighting your scope 0 at 100 yards, it maintains +/-1" off sight line (2" point blank range) from 80 to 220 yards. Mounting to your upper receiver picatinny rail, the DSS is a solid scope mount with extremely accurate on/off repeatability. The height allows for see-through vision of your close range sights and allows your stock to rest securely and comfortably against your shoulder instead of on top of your shoulder for more accurate long range use. It is also a convenient carry handle for those long excursions. Its rugged design will not only compliment the look of your rifle, but is CNC machined from aircraft quality 6061 aluminum for strength and hard anodized for durability. The Mil-Spec picatinny rail gives you mounting options for most scopes and other accessories such as camera mounts or tactical flashlights for outstanding nighttime home defense.

One of the significant advantages of the DSS is the unique trajectory created by the extra height. With your scope sighted at 0 at 100 yards, it maintains +/-1" off sight line (2" point blank range) from 80 to 220 yards and +1"/-3" (4" point blank range) from 25 to 255 yards.
