None of the other SMGs will ever require six shots to kill, making them much better fits for Silencer usage. The lesser time between shots will cause recoil to compound more easily, but the PP90M1 has low enough recoil values and an unusually self-centering recoil profile to offset such a disadvantage.
Extended Mags is a very worthy attachment choice for the PP90M1, increasing the PP90M1's magazine capacity to a huge 54 rounds, and increasing the starting ammo loadout to a large rounds. This will help to make reloads infrequent with the PP90M1, lessening the need for Sleight of Hand, and the extra ammo loadout lessens the need for Scavenger. Extended Mags is an attachment choice that is very safe, conferring no downside, and only helps the player.
The first infected will also receive a PP90M1. However, it will have Range and Extended Mags equipped. Because of its rather high damage up close, high fire rate, and decent amount of ammo, it is an effective weapon in close quarters combat.
Sleight of Hand is a necessity for its long reload time. It performs very similarly to its Call of Duty: Modern Warfare 3 counterpart; both have the same magazine capacity, low recoil, and good hip-fire accuracy.
One difference being that the muzzle flash has been increased dramatically. In single player, it is used by Russian forces in various missions. Call of Duty Wiki Explore. Cold War.

Weapon Armory. Air Support Armory. Equipment Armory. Helical magazines have been used in firearms as early as with the Evans Repeating rifle.
The Evans could hold 34 rounds of. The magazine separator is driven by cycling the lever action. Helical magazines are probably best known from the Calico series of carbines and submachineguns with magazines holding between 50 and rounds of. Photos of North Korean Type88 rifles with helical magazines have also surfaced.
The magazine capacity is unknown, but estimated to be around rounds. Helical magazines all have different designs, but their principles are more or less the same, and they all have one thing in common: High capacity in a compact package.
But how do they work? Lets have a look:. To illustrate the principle behind helical magazines, I'll use the next couple of pictures to transform an ordinary double-stack 40 round stick magazine into a helical magazine. This magazine is not an accurate representation of a particular magazine, but rather an illustration of the concept as a whole. A normal magazines has a spring blue that pushes on a follower red , which pushes the cartridges toward the top of the magazine where they are fed into the chamber by the bolt.
You will notice that the spring takes up quite a lot of space in the magazine. The first step toward turning this magazine into a helical magazine is to slant it forward. With the magazine slanted we can now twist and curl it up.
We now have a 40 round magazine body that is a lot more compact than the stick magazine, but an ordinary coil spring would not be able to fit run inside of it. The solution to this is both clever and elegant:.
First we cut out the inner wall of the magazine red , remove it, and replace it with a slotted cylinder called a Separator green. The slots of the separator holds on to all the cartridges in the inner row, and as the separator rotates it pushes the cartridges along with it, as seen in this animation.
We now need to add a follower red. The follower fits into one of the slots of the separator and can slide back and forward. The follower is not necessary on helical magazines that are single stacked. The last step is to add a spring blue.
