Closing thoughts

The MP5-SD is a silenced SMG that occupies the same loadout slot as the MP7; it's unique selling point is its silencer as the former deals more damage. Unfortunately this often is not enough to justify its high purchase price. However, a cheap (compared to a rifle) weapon that is silenced and has a high rate of fire can have utility in certain scenarios.

Generally strictly worse than most other SMGs given it costs $1400, the PP-Bizon has only the unique selling point of a huge magazine which can fire 64 rounds without a reload.
