Brand: GG&G GGG-1006RA
The MAD BUIS With Ranging Aperture was originally manufactured by GG&G under a contract with Picatinny Arsenal, and although it is ammunition and weapon specific, we decided that it was time to offer it to a broader market.
The adjustable back up iron sight has all of the same great features as the standard MAD BUIS (back up iron sight) such as 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, it has one important exception: it is also a ranging sight. The unique rotating multiple aperture disc has 5 apertures preset to specified distances. In particular, 0=25 and 200yds 3=300yds 4=400yds 5=500yds 6=600yds. A small window facing the shooter, as can be seen in the above photograph, provides a numerical cue as to the range. All apertures are the same diameter--.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's rotating aperture sights go beyond the performance of a normal backup iron sight thanks to their low profile, snug installation, and field tested accuracy. Because our aperture rifle 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.
