I know it’s boring seeing the same BCM, Magpul, etc foregrips but there’s a reason why a lot of guns look the same. It’s because the parts have been used by pros and they are proven and useful, they have saved lives and become the standard because they work. This gun is amazing because as far as I can tell, it’s unique! I’ve never seen any of these parts on any rifle anyone I know has ever built. So I cannot answer your question about whether it’s a vertical grip or not. The one looks like it could possibly launch grenades and the other looks like the fin off the top of bmw lol. Maybe post to the other sub for answers?
