The GG&G Adjustable Back Up Iron Sight has all of the same great features as the standard GG&G MAD BUIS, including its low profile, solid 4140 steel and 6061-T6 aluminum construction, solid locking detent with button release, and mil-spec finish. Unlike other adjustable sights, this Folding Sight has one important exception: it is also a ranging sight.
The GGG MAD Ranging Sight features a unique rotating multiple aperture disc has 5 apertures preset to specified distances. A small window facing the shooter, provides a numerical cue as to the range. All apertures are the same .070" diameter. The apertures have been preset using the ballistic calculations for 55 grain through 62 grain ammunition used in the AR15/M16 16" carbine length weapon. GG&G Rotating Aperture Sights go beyond the performance of a normal backup iron sight thanks to their low profile, snug installation, and field tested accuracy. These GG&G Rear Sights are designed for real world tactical use by police and military personnel, they have qualities that go beyond cheap imported knockoffs found elsewhere. The GG&G MAD Backup Iron Sight with Ranging Aperture is a bestseller thanks to extensive word-of-mouth endorsements by marksmen and armorers around the globe, so you can count on it whether you're on the range or out in the field.
Compatible with the M-16, AC Carbine, and the AR10 Rifle, the GGG MAD Ranging Sight is attached to a mount body that is CNC manufactured from billet 6061 T6 aluminum alloy and Type III hard coat anodized in a non-reflective black mil-spec finish to provide combat durability.
