PK-AS or Kobra will probably match what you're looking for.
The PK-AS sits offset to the left of centerline since it goes straight up from the optics rail. The PK-AS-V is the version that sits over the centerline of the rifle, but due to it's construction it sits pretty high. You'd definitely want some kind of cheek riser to counteract the chin weld you'd get from it. The bad news is they stopped making new ones a while back, so you're only going to be able to find them on the secondary market these days.
The Kobra is a good optic, but they've become relatively expensive these days. Though I honestly don't know of another optic that has a chevron like it. The Gen 1+ Kobras seem to the most popular, but you may find a Gen 2 floating around on the EE or something. The Gen 2 has a better layout of controls, though the power switches are notorious for breaking. Also, finding a sunshade for the Gen 2's is much harder, and the Gen 1+'s pretty much all came with one.
