Precision manufacturer Ultradyne has released their revolutionary new C4 Sighting System. Much more capable than standard back-up iron sights (BUIS), the C4 Sight system offers precision with the ruggedness and low profile of folding sights.
The C4 Front Sight is the first of its kind, bringing precision front aperture technology to backup iron sights. The interchangeable front sight apertures provides options never before available from folding sights. The rear sights provide elevation adjustment from 200 to 600 yards.
Ultradyne’s unique design keeps the fully-adjustable front sight post centered between protective ears, the entire unit moves when you make adjustments. No more annoying front sights off to one side. The Dynamount front sight restores your sight radius to full rifle length while eliminating the negative effects of free-float hand guard deflection.
The four proportioned circles of the front and rear apertures and protective ears align instinctively upon shouldering the rifle. Dynalign keeps your sight picture the same regardless of windage or elevation adjustment so every shot feels like the last and trains you for the next. The rear sight allows tool-less, on-the-fly windage and elevation adjustments, just like a magnified optic.
Don’t let the precision adjustments fool you, C4 sights are rugged. Both front and rear are 100% CNC machined from 4140 steel and 7075 aluminum and protected with salt-bath nitride and anodized finished.
Rear sight includes two insert sizes with one stored in the elevation knob.
Front Sight includes 10 MOA globe sight. 8 MOA, 12 MOA, 14MOA, and blade posts available.
