The MP7 is optimal at close range. The submachine gun boasts a blistering fire rate of 900 RPM and one of the highest damage outputs in the SMG class.
To compensate, the MP7 has relatively high vertical recoil compared to other SMGs, and is unable to be customized with a grip. In addition, unlike most iron sights, the default MP7 iron sight obstructs vision minimally when aiming.
Prior to an update, the charging handle on the MP7 was partially retracted which would have left the gun unable to fire. This has since been fixed.
Prior to the release of Operation Dust Line, equipping any optic with the MP7 would give it unusable Night Sights. However, when the lower magnification optics were equipped, the green glow of the Night Sights would occasionally block the field of vision. This was fixed by completely removing them when optics were equipped altogether.
