Ultradyne C2 Fs Aperture

The Ultradyne C2 FS Aperture is a precision front sight engineered for rapid target acquisition and accuracy-focused shooting disciplines. Machined from 416 stainless steel and aircraft aluminum, this compact aperture sight delivers the strength-to-weight ratio critical for duty and competition applications without adding bulk or mass to your rifle platform.

The 12 MOA aperture opening provides the optical advantage of fast sight picture acquisition while the fully adjustable windage and elevation knobs enable precise zero establishment and hold corrections. This optical geometry—combined with the enhanced clarity and reduced parallax characteristic of properly designed aperture optics—creates the conditions for consistent accuracy across variable distances and light conditions. At 0.19 lbs, the C2 FS integrates seamlessly into build packages where every ounce matters, whether optimizing for maneuverability or maintaining dynamic handling characteristics during extended duty cycles.

This aperture sight suits shooters transitioning from magnified optics to iron sights, patrol operators maintaining sight system redundancy, and precision rifle competitors who demand repeatable mechanical adjustments. The FS designation indicates front sight positioning optimized for standard AR-platform and similar tactical rifle configurations. Operators and competitive shooters value aperture sights for their mechanical reliability, zero retention under recoil, and performance across variable environmental conditions where electronic or battery-dependent systems introduce complexity.
