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