Since the charging handle was made ambi, expect to rip up your hand when charging from the left hand side. Mine just has a small nub and ripped part of my thumb open on it. I can see why they had it on there, in prototypes then took it off in production. I heard they were going to offer it as an after market part, but honestly I much prefer just bringing the charging handle back a bit to drop the bolt.
Mine appear to stick out / be more proud than the one in the photo, in the photo about it looks a lot closer to flush.
