Ultradyne
Overview
The C2 Folding Offset Rear Sight from Ultradyne is a rear sight designed for versatility and quick deployment, featuring a folding mechanism that allows it to stay out of the way when not in use. This sight does not include illumination, which keeps its profile low and simple, making it ideal for use in various lighting conditions without added complexity. Builders often incorporate this rear sight in tactical setups where a backup sighting solution is needed alongside optics.

Build history on GunPartPicker
Builders on GunPartPicker first added the Ultradyne C2 FOLDING OFFSET REAR SIGHT to a build in May 2026.
It was hard to find in September 2026, in stock on only 3 of the 19 days we checked, and today only Optics Planet has it in stock. It dipped to $72.18 at BattleHawk Armory for a stretch in September 2026, well under its usual $89.99, so sales do come around. Buying today, the lowest price is $99.99 at Optics Planet, above September's low of $72.18, so a better deal may come back.
