Ultradyne Advances Rifle Marksmanship With New C4 Sighting System

Precision manufacturer Ultradyne has released their C4 Sighting system.  While taking the same position on your rifle as standard back-up iron sights (BUIS), the C4 Sight system offers more than just back up. 

Dynamount Front SightC4 sights are engineered for accurate shots at both close and extended ranges. Changing the way you use “iron” sights, the C4 system does more than simply point the rifle in a general direction.  Greater care, attention to detail, and engineering have gone into the creation of the Ultradyne C4 system than any other set of folding sights.


Ultradyne Front Sight

It starts at the front.  Ultradyne’s unique design keeps the fully-adjustable front sight post centered between protective ears.  By enabling complete adjustment of the front sight, the rear sight remains free for tool-less, on-the-fly windage and elevation adjustments, just like on a magnified optic.  Opt for the Dynamount version and restore your sight radius to true rifle length while also eliminating the negative effects of free-float hand guard deflection.

Ultradyne Rear SightThe 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. 

Despite their meticulous precision, 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.

“C4 precision folding sights permanently changed my perception of what was possible without magnified optics.  I was quickly making solid hits on small targets well beyond ranges I would have previously attempted,” Aaron Lisech.

Brownnell’s has produced an excellent video demonstrating the C4 system:
