The NC05 Jackhammer is the New Conglomerate heavy shotgun available exclusive to Heavy Assault. With unique 3x burst mode, it can mow down enemies at close range almost as fast as pump action shotguns. The Jackhammer is essentially a shotgun that has bigger magazine than regular shotguns, has fewer pellets and deals less overall damage, but have no damage drop, and has a 3x burst mode. Because of the burst-fire mode, it is highly recommended to use an extended magazine. The burst-fire mode also increases the Jackhammer's fire rate to around 450 RPM, although there is a split second of chamber time after each burst.
Since Jackhammer has no damage drop, theoretically its effective range is only limited by pellet spread and pellet velocity.
It is possible to get both Ribbons and Medals for using the NC05 Jackhammer. Each Ribbon is a standard reward for achieving a set amount of kills with the Jackhammer. Medals relate to how many overall kills you have with the Jackhammer.
