Good deal. Yes, they look to resolve my issue w/ his Gen 1s, which was they were oddly wide, and squat -- but haven't tried them. However, I would still like to see the top rail edges extend out to the outer edge of the lower rail. As is, stones, etc, can fall into the handguard via gaps between upper and lower. Granted, it's less of an issue now with the mlock cutouts allowing stuff to more easily fall out than gen 1, but it should also allow the upper to be made a little more rigid... As is though, not having it extend to inline probably does keep it from being impacted and damaged quite as much, and allow the upper to remain a little lighter in construction.
Regardless, what's been you impression with these? Good to go?
