In a nutshell: DELET THIS!!

This semi-automatic anti-materiel rifle capable of firing 25x59mm explosive payload rounds as well as .50 BMG anti-materiel cartridges. both IMC and Militia pilots generally found the PB-504's reduced weight and its semi-automatic fire mode a worthy trade-off.

In-game short description

The PB-504 Anti-Materiel Payload Rifle (PB-504 AMPR) is a Pilot semi-automatic .50 cal/25mm anti-materiel rifle and sniper grenade launcher, appearing in an upcoming Titanfall 3: Milkdromeda. It is developed by Paradinha Arsenal and Wonyeon Defense.


The PB-504 AMPR is a semi-automatic anti-materiel sniper rifle that fires a 25x59mm payload rounds, typically high-explosive one, much like a real-life counterpart, Barrett XM109, in addition to .50 BMG anti-materiel rifle cartridges. It is the lighter but a much faster rate-of-fire equivalent of Kraber-AP Sniper that deals little less damage. It can be chambered in either ten-round .50 BMG or six-round 25x59mm detachable-box magazine.

The PB-504 can be either an anti-materiel sniper rifle, or a direct-fire grenade launcher depending on some situations.

Bullet velocity for 25x59mm rounds are much slower compared to the .50 BMG variant, much like Neopup PAW-20 direct-fire grenade launcher.

The sophisticated fire-control system, or active recoil compensation in other words are integrated into PB-504, designed to compensate for 25x59mm's intense recoil.

Both versions of PB-504 AMPR are based on the belt-fed Mag Launcher, converted into a semi-automatic, magazine-fed anti-materiel rifle.

The design for the standard version of PB-504 AMPR is vaguely similar to a Barrett M82A1 anti-materiel rifle, but generally futuristic.

The design for lighter, bullpup version of PB-504 AMPR is vaguely similar to a DSR-50, the big differences is that foward magazine holder is replaced by a carrying handle similar to Intervention sniper rifle, and it is semi-automatic rather than bolt-action.
