Ultradyne

The Dynalign sight picture provides more accurate and faster target acquisition using a purely concentric sight picture that is similar to that used by Olympic target shooters. Unlike red-dot or holographic sights this sight picture does not obscure the target and actually enhances visibility due to the optical characteristics of apertures. - Most BUIS systems utilize a sight picture that is non-intuitive. The brains visual systems are asked to align a circular rear aperture with a rectangular front post shape while simultaneously ignoring the ears that protect the front sight post. Dynaligns circle-within-circle sight picture allows for faster sight picture acquisition. Additionally the use of a front aperture further reduces parallax effect which makes accuracy less dependent on precise sight alignment. - In addition to its revolutionary sight picture the C4 Front Sight provides additional features: - TOOL-LESS ELEVATION ADJUSTMENT - Make hassle-free adjustments anywhere anytime. - WINDAGE-ADJUSTABLE FOR ZEROING - Regain full range of rear windage adjustment and guarantee center-zero operation. - MULTIPLE FRONT SIGHT PIN OPTIONS - Choose from traditional post or multiple Dynalign front apertures. - 100% CNC MACHINED IN THE USA - American-made quality. - C4 Precision Folding Front Sight Technical Specs - Apertures - 12 MOA Dynalign & Front Post Included - 8 10 and 14 MOA Dynalign Available - MOUNTING MIL-STD-1913 Picatinny Rail .223 / 5.56 Dynamount .308 / 7.62 Dynamount - WINDAGE ADJUSTMENT - 40 MOA Total - 1/2 MOA Per Click - ELEVATION ADJUSTMENT - 28 MOA Total - 1 1/4 MOA Per 1/4 Turn - MATERIAL - 4140 CrMo Steel Salt Bath Nitride Finish - 7075 Aerospace Alloy Hard Anodized - MASS - Picatinny: 62g / 2.2oz - .223 / 5.56 Dynamount: 62 grams - 2.2 ounces - .308 / 7.62 Dynamount: 62 grams / 2.2 ounces - DIMENSIONS - Picatinny: - 31mm / 1.21in Wide - 9.4mm / 0.369in Height (Stowed) - .223 / 5.56 Dynamount: - 31mm / 1.21in Wide - 9.4mm / 0.369in Height (Stowed) - .308 / 7.62 Dynamount: - 31mm / 1.21in Wide - 9.4mm / 0.369in Height (Stowed)
