Troopers who have a Morita Mk1 Weapon Mastery 6 or greater will be able to attach an underbarrel to their rifle via the loadout menu. The underbarrel comes with a 4-round internal tube as well as 8 additional shells for reload at the cost of one of your traditional Morita Mk1 magazines. Additionally, the extra weight of the Underbarrel causes the weapon to be a bit heavy on the frontend causing it to be a bit more inaccurate when firing on the move or from a standing position.
MK1 6级之后将能够部署下挂霰弹，4/8的携弹量。代价是减少一个弹匣，枪变得更重，移动中精度下降。

还是画大饼，之前说要出下挂系统，瘪了妮玛的三年最终就憋出一个原版的下挂霰弹配件。我还以为有榴弹什么的呢
