Attachments listed for TTK and BTK were tested on a player with no body armor and no additional attachments on the gun.

PBX 45 Time to Kill (TTK)

The TTK was computed by using the following formula: (60/Rate of Fire)*(BTK-1).

It comes as no surprise that the Close Combat ammo type will be the best attachment for close-range fights(0-30m) and then swapping to the Standard Magazine for mid-range. Though the High-Power Magazine has a good TTK for anything beyond 30m, SMGs aren't an ideal weapon to use at that range.

Attachment Loadouts

Best Attachments for Close to Mid-Range

For the scope, the best sight attachment would be the Fusion Holo for minimal screen clutter. If you need a bit of extra magnification, the 8R Holo is a solid choice that doesn't sacrifice aim-down sight speed.

The best ammo type for the PBX 45 would be the Close Combat magazine. This magazine will increase your time-to-kill (TTK) drastically, making it worth the slot. However, if you're playing in a map that has more open areas, the Standard Issue / Extended Mag is a solid choice that can help you compete against other rifles at mid-range.

The BCG Light Grip is the best grip for the PBX 45. You will be in close-range fights often, so an attachment to increase the gun accuracy while moving is needed.

Lastly, the best barrel attachment for the PBX 45 has to be either the Champion Muzzle Brake or the 6KU Suppressor. This gun does not have a lot of vertical recoil, so fixing the horizontal recoil instead would be the best option. If you find yourself attacking a heavily contested objective, a suppressor like the 6KU will help you keep off the enemy minimap.

Best Specialist for PBX 45

Specialist	Strengths
Paik	Paik's EMG-X Scanner Specialty will highlight any enemy within a 30m radius around her. Use this in conjunction with smoke grenades to get easy kills through the smoke.
Mackay	The PBX 45 has a decent range, which Mackay can take advantage of thanks to his Grappling Hook Specialty. This gun will be serviceable for both assaulting enemies up high and shooting down at enemies from above.
