This is a recurring issue. Guns are jamming at a very high frequency.
4 different guns with 4 different players. All guns pristine and ammo pristine. All 4 guns jammed at the same time resulting in 4 deaths. The same guns kept jamming prior to that. Ammo is scarce as it is. 4 hours of looting to die by guns jamming at the same time when everything is pristine.
