I'm currently running a Barska holographic sight on my 15-22. I chose to go with the holo type red-dot so I can get a better overall field of view. It's mounted on the top rail with no adapters or risers. Once I got it dialed it, it's pretty accurate for the price. I just started shooting a rifle after a couple of months with pistols, so I'm working on my technique. At 75 feet, I can manage 2" groups without a rest or bipod.

Picked it up at Big 5. Tag said $54.99, but it was on sale in addition to an e-mail couple. Before tax, it was $34.99.
