Is the JAK Headhunter Carbine Conversion Worth It?

Yes, the JAK Headhunter carbine conversion is worth it. It has exceptional bullet velocity and range, gun kick control for days, and admirable damage. We especially love the recoil controls, which helps out a lot with long-range offense. There are a few downsides with this conversion, however, such as low aim down sight speed and bad hip-fire spread. It also reduces your movement speed a but, though it’s more than made up for with all of its other positives.
