I feel like this attachment is kinda genius but it’s so obvious that I must be missing something. Like how have I never seen this before. It’s just mace on the front of your gun. This isn’t my set up by the way. I tried posting on another page but it got taken down like right away so I’m trying here for opinions

Bro you can just have mace on the front of your gun? How has this never been thought of? Or am I just an idiot is there like some major flaw I’m not seeing. This isn’t my set up by the way I’m looking to get a 300 blackout subsonic and ran into this attachment
