Fast Deployment In Emergencies; Multiple-Setting Aperture For Precise Accuracy
Originally manufactured under contract for Picatinny Arsenal, the MAD (Multiple Aperture Device) rear sight gives the tactical shooter a dependable, fast-deploying back-up sight system with preset range points out to 600 yards. A robust locking bar and cross-bolt clamp the MAD securely to the rearmost slot in any Picatinny-style flattop receiver rail. Rotating disc has five numbered .070" apertures preset to provide the right elevation for quick, short-range engagements or precise accuracy at longer distances: 0 – 0 to 200 yards, 3 – 300 yards, 4 – 400 yards, 5 – 500 yards, 6 – 600 yards. (Calibrated for 5.56 NATO ammunition with 55-62 grain bullet fired from a 16" barrel.) Position number is clearly visible to the shooter through a window below the aperture. Easy-to-grasp serrated windage adjustment knob provides approximately ½ MOA adjustment per click on standard-issue M16A3 rifle and .65 MOA on M4 carbine. Co-witnesses with most non-magnifying holographic and red dot optical sighting systems. Folds down out of the way for low-profile storage when not in use; radiused edges and rounded corners help prevent snagging on other gear. Folded MAD overhangs the upper receiver by approximately ¼", providing a lip for solid thumb contact to deploy the sight instantly, even when the operator is wearing gloves. Locking detent ball prevents the raised sight from accidental lowering; the operator must depress a spring-loaded release button to lower the sight. Precision machined base of strong, hardcoat anodized 6061 T6 aluminum and sight tower/aperture wheel of Parkerized 4140 steel handle the punishment of high-tempo combat operations.
