The H&K MP7 is a 40-round SMG with low damage-per-shot and a very fast fire-rate, giving it decent damage-per-second but not the greatest. It has good mobility and a quick reload speed, but its accuracy is low and its recoil is high. Despite its low damage-per-second, the H&K MP7 has fairly low damage fall-off, giving it some usability at mid-range; though, the effective distance is low. The most significant advantage of the H&K MP7 over other similar SMGs is its rather large magazine size, allowing more room for error; it also has fairly high ammunition reserves.
Overall, the H&K MP7 is a great SMG for close-range combat. With a high magazine size and high reserve ammunition, the H&K MP7 is a very reliable weapon in small Deathmatch maps like Bay 5.
