In many cases, mounting a scope as low as possible is good advice. But with the AR-15 platform, it's usually best to mount the optic so that its centerline is ~1.5" above the rail. Stock design, shooting style, and individual facial structure come into play, but ~1.5" works for most people.
Individual rings work fine, but it's somewhat dependent upon the design of your preferred scope (such as turret placement, eye relief, etc). It's suggested to mount both rings to the upper receiver, and avoid mounting the front ring on the handguard (unless it's a true monolithic design where as upper receiver and handguard are one piece). If the scope will allow both rings to be mounted on the upper receiver, and at the right height with proper eye relief, any quality rings should serve fine.
If this isn't possible, there are numerous cantilever style mounts specifically for the AR-15 that will work, or a cantilever picatinny riser will work too.
Note that not all ring manufacturers measure ring height the same. Some measure to the bottom of the ring, while others might measure to the centerline. Also, some are designed for picatinny and others weaver rails, and some might work on both, but I suggest using rings specifically for picatinny rails. If you go with a riser, adjust ring height accordingly.
Obviously, I haven't given you anything specific, as I generally use scope mounts designed for the AR. Brands such as Burris, LaRue, ADM, and Bobro come to mind. The Burris PEPR (available in 1" and 30mm sizes) is one of the less costly options that usually works well.

If you choose rings or rings / risers, just be sure to focus on height and eye relief, while attaching only to the upper receiver. Or choose a mount that already takes these factors into consideration.
