Harris is the popular benchmark for bipods. If there is a weakness it would be how it connects to the gun via a small button. AR's typically have MIL STD 1913 rails on the handguard so you'll need an interface button to connect a Harris. You can either use a quick detach which has this button, or have the button permanently attached.
The LaRue LT130, GGG 1406 and the Badger TRAMP are examples of quick detach rail mounts with the Harris button (I've used the LT130...It works, but makes the interface bulkier and heavier than it could be). Or you can permanently fit a Harris connector button to the underside of your handguard, if it is possible to do this (like the Samson Leymod Harris adapter; http://www.samson-mfg.com/product/KM-BIPOD-KIT.html
Or, you can remove the Harris button and replace it with something more solid. Badger has recently introduced something called their, Low Profile Harris Mount:

The downside is you can't take it on and off in a hurry like the quick detach mounts or even using the standard button and Harris' replacement wheel for screwing it on/off. The upside of the LPHM is the Harris is closer to your handguard and it's a solid fitting that does not rely on a single small button for interface. To be honest I have yet to use the LPHM so cannot comment on it other than say it is a recent innovation and on spec it solves an issue that concerns some.
I have a couple of Harris, with the notched legs.
Beware of counterfeits. All popular brands have been copied by the Chinese; Harris, Atlas and even the GGG 'freak's' talking about.
