Ultradyne has launched their C2 line of sights for AR-15s and rifles/pistols requiring a similar sight setup. These sights retain much of the function of their original C4 sights but come in a lighter in weight and easier on the wallet. If you are wondering what makes Ultradyne sights unique, I suggest you take a look at Kit Badger’s recent review of the C4 sights as their sight picture is probably best shown on video.
The C2 folding sight line is available in both traditional rail mounted versions and right hand offset versions. They are made from 416 stainless steel with a nitride finish and 6061 aluminum with a hard anodized finish. The new C2 sights are lighter in weight, lower profile, and $100 less expensive for the set than Ultradyne’s C4 sights.
