$85 for a YHM quick deploy iron rear sight or spend more and get an ARMS or Daniel Defense or Troy or Larue. But the YHM is good for the money.

PMags by Magpul are great mags for about $14 each. We recently discussed sights and mags in a tread by another BB rifle purchaser.

If you want a good reddot for less than $100, get a Primary Arms M3-ish multi-reticle. I have two and they are rock solid. You can get outfitted with a mount for about $100. No need to spend big bucks on a mount. Marshall (Primary Arms owner) is great to work with and buying from him is as hassle free as I've ever encountered. He usually ships the same day on instock items if you submi an order before noon.
