Combine those three pieces, then remove the original HK MP5 Upper receiver to replace it with the silenced one you just created. Then transfer the stock and the rearsight over from the old receiver as well.
The MP5 version used in Escape from Tarkov is the MP5-N, a model designed for use for the United States Navy, which includes a Navy trigger group (including safe, single fire, 2–3 round burst, and full automatic).
Three variants of the MP5 are present in Escape from Tarkov's predecessor, Contract Wars, a PvP multiplayer game also by Battlestate Games. They are the MP5K, a shortened version of the MP5 and tier 1 submachine gun, the MP5SD Spec, a SPEC weapon submachine gun, and the MP5SD6, a premium tier 1 silenced submachine gun.
