Why is this not standard??? - Aero Precision AR15 Ambidextrous Bolt Release ,PDQ

I was a little hesitant because of the modifications I would have to do to my lower to put this in....I took my time and realized it was EXTREMELY easy to do.....just take your time when you do it for the first time or two. This is a feature that I feel should be a standard on all AR15s. I have put these into all of my lowers. Before this, I had Magpul BAD levers in all of my rifles...but I kept actuating them inadvertently because I have pretty fat fingers. Add to that, the fitment of the levers wasn't always 100% and there was usually a bit of wiggle in all of them. They're all gone now because this simple lever does the job easily and is very functional
