If I were looking for an inexpensive red dot for a 15-22 I'd personally recommend one from Primary Arms. They have a really good reputation (considering that they are knock-off optics) and are fairly inexpensive. Last I checked, however, they were in short stock. I'm guessing they are waiting for a new shipment from their manufacturer in China.
