LumaShark Integrated Flashlights In A Gun Rail But Why Tho

I give this a 1 sigh, 2 whatevs, and a grumble:

$400 on their website.  “Patented” too apparently.  People are always trying to corner every micro-niche in every market.  No one is copying your idea dude.  We made it from the Vietnam war era until 2017 where the technology to do this has been available.  It’s an obvious idea and no one else did it…. for a reason haha.

Thoughts?  When is the integrated bipod coming out?  The integrated optic perhaps? An integrated barrel?
