Type 95 SD JGLEdit
It is not necessary to customize this weapon as it is one of the best guns in the game in the Jungle configuration. In addition, buying and subsequently using this weapon to the exclusion of all others is the kind of thing that is highly indicative of lacking the necessary intellectual fortitude to make educated modding decisions anyway.
The Type 95 SD JGL boasts very accurate fire on single-shot, three-round burst, and fully automatic fire. As such many players replace the front grip with a bi-pod and fit a scope capable of medium zoom so as to be able to fully dominate battlefields in CQC, mid-range, and long range engagements.
Alternatively players can simply spray the weapon on the fully automatic setting and collect a 5-star rating in short order.
