(5 customer reviews)



Packs all the high-quality features Ultradyne is known for into lightweight, compact, sight system. Fully machined from the perfect combination of 416 SS and aircraft aluminum to maximize strength and weight. The rear sight boasts a positive click oversized windage knob which serves as storage for the .070 aperture when using the ghost ring. The C2 Front Sight System makes sighting in a breeze by offering both windage and elevation adjust-ability. The C2 Sight combo offers a dual aperture system that features a 12 MOA front sight aperture and gives the advantage of lightning-fast target acquisition while improving accuracy. Improved accuracy is created by the enhanced clarity and reduction of parallax due to the optical characteristics of the C2 dual aperture. In addition, the C2 enables the shooter to see 100% of the target, not cover it. This promotes proper shooting techniques and allows the shooter to focus on the only thing that matters, the target!

  1. R.G.

    I was considering the usual suspects that made BUIS, but wanted to try something different. I’m glad I did. There are a lot of competitors in this price range but I think there are enough features to warrant checking these C2s out.

    I’ve never had a front post with an aperture but after trying it out I can see the merits. Being able to see your target at extended ranges is simply better than guessing with a giant front post. If the aperture isn’t your thing, they offer a version with a normal front post; so don’t let that hold you back.

    The sights have a very strong detent preventing them from folding unexpectedly. The windage knob has a tactile detent. The elevation works like a Wheeler torque wrench where you pull the dial down against a sprint and rotate it one ratchet click. Every control is simple and has a positive lock that gives me confidence that they will stay where I set them at.

    As someone with a machining background there are a lot of products out there that make me feel like I didn’t get my money’s worth; this is not one of them.

    I don’t usually leave reviews but when I received my set of C2 sights I had too. These are by far the best manufactured BUIS I have ever come across, the machining and finish work on each piece is absolutely top notch, smooth, no milling lines or chatter marks, the threads are all butter smooth, the detents are perfect and not “notchy”. Simply put these are the nicest set of BUIS money can buy, period. I own at this moment Troy’s, KAC’s, LWRC’s and a host of others, these are hands down the nicest made. Even the screw-in diopters are machined steel, I was totally expecting them to be plastic! It almost makes me feel foolish for spending more than twice on a set of KAC’s. A set of these will end up on each of one my carbines. Thank you for your attention to detail and for offering these at such a fair price for the quality you provide. Ed

    The dual aperture system is by far the best. These sights check all the boxes at a real good price.

    I bought a pair of these sights for my AR-10 and I can’t say enough about them. They’re easy to mount, easy to sight and my shooting has gotten much better. I would and have recommended these sights to anyone who’ll listen. I let a couple of friends try out the rifle and they were all impressed.

    Just wanted to let people know that C2 sight is pretty great, I put it on my ar chambered in 7.62×39 and I was hitting steel plates at 200 yards with ease and even 250 yards and these were only torso size targets at the largest.
