Ultradyne C2 Rear Sight

The Ultradyne C2 Rear Sight is a precision-machined rear sight engineered for operators and competitive shooters demanding lightweight performance without sacrificing durability. Constructed from 416 stainless steel and aircraft aluminum, the C2 delivers the rigidity required for tactical and precision rifle applications while maintaining a compact footprint that keeps your sight picture clean and your rifle balanced.

The oversized windage knob features positive click adjustment for repeatable, precise elevation changes—critical when zeroing or engaging targets at distance. The knob doubles as secure storage for the .070" aperture when you're running the ghost ring configuration, eliminating the need for a separate pouch or loose components. This dual-function design reflects the engineering philosophy behind Ultradyne's rear sight: every feature serves a purpose. The combination of 416 SS and aluminum optimization balances strength-to-weight better than steel-only alternatives, reducing fatigue during extended operations while maintaining the rigidity needed for consistent accuracy.

The C2 is purpose-built for AR-platform rifles and serves law enforcement, military, and civilian marksmen running 5.56 NATO, 300 BLK, or other common rifle calibers. Whether you're building a duty carbine, a precision rifle for match shooting, or a field rifle for hunting applications, this sight integrates seamlessly into modern optics systems as a backup or as a primary iron sight for close-quarters scenarios. The sleek profile and refined machining quality ensure compatibility with standard Picatinny rail systems and co-witness setups with red dots and magnified optics.

Ultradyne USA rear sights are favored by those who understand that sight selection directly impacts rifle handling and shot placement. The C2 delivers exceptional value for operators and shooters who refuse to compromise on materials or precision manufacturing.
