The customer that ordered the CAWS overhaul brought in another prototype weapon - a Pancor Jackhammer. Again he ordered an overhaul of the weapon. He wanted a changed, more ergonomic pistol grip and a matching foregrip, a built-in laser pointer, a G36-styled RIS, an HK-styled trigger, a custom handguard, and a SPW RDS with added support iron sights.
