Ever been stuck on a CQB situation where your gun jammed or your mag is empty and your opponent is about to shoot your ass off and hes few inches far from you, to solve this type of situation you would switch to your secondary, but it's empty too!(doubt you'd even have the time to unholster it) you'd think that the best solution is to simply throw a fucking muzzle punch directly on your opponents nose but oh noes, this feature is not implemented yet!!
add a feature where you can throw melee attacks with the muzzle of your gun, or its stocks, would be customizable
this would open opportunities for bayonets on guns
(yes they are very life saving)
