This is one of the best accessories I've ever owned- I now have two. We used them in Iraq on both our M4's and on our M249's, and they worked GREAT! They really took a beating, and kept on going. Occasional (very rare) issues with sand/heat gumming up the bipod-extension mechanism, but extremely easy to fix/clean when this happens. In addition to the bipod being sturdy enough to stand up to full-auto fire use, it also provides a rock solid forward grip for positive control of your firearm. I teach black rifle courses, and this is my number 1 recommendation- I don't like to use any other vertical foregrip.
