BPB-M50

The BPB-M50 is a large caliber fully automatic single barreled rotating spring integrated weapon.

## Specification

The BPB-M50 uses a Bullpup design to integrate a large back slung magazine which holds 1000 rounds of 8.25x10 AP shedding core ammunition\*. The rotating spring designed to fit the BPB-M50 allows for the fitting of an inertial bolt which recoils with the bullet to allow for the suppression of recoil out of the barrel instead diverting the recoil into the rotating spring which in turn disperses and exerts any force still remaining into the shoulder stock of the weapon. The most recognizable feature of the BPB-M50 is the high automatic rate of fire which can be adjusted to fit the needs of the user, the starting rate of the weapon measures in at 1600 rounds per minute which clears 26 rounds per second, this insane rate of fire is causes the need for such complex means of recoil dispersion due to the imparted force upon the weapon.

The weapon can be cycled to fire at lower rates such as 1000 rpm 800 rpm 600 rpm and 200 rpm this is a feature designed to suppress enemies for longer or to make the weapon fire more accurately at longer ranges, however bipods are also standard on the weapon which are deployed via the grip of the weapon. The added benefit of a toggle of fire rate allows for what some soldiers describe as overclocking.

### Overclocking

Soldiers in the field take to the common habit of taking apart their weapons and overclocking their fire selectors, this has a very negative side effect upon the weapon and can make its lifespan significantly shorter than intended, often warping the barrel of the weapon if fired for too long. The maximum known achievable rate of fire for the weapon is a speed of 2400 RPM which takes a massive toll on the parts used to propel the round as they are forced to work at higher, more damaging speeds. This has a worse effect on the user in short term as the weapon itself is not capable of cycling the spring fast enough to mitigate recoil. The bullpup design however allows for the weapon to fire at this speed rather than just jamming and destroying itself, this tactic of overclocking is frequently used when it is expected to meet green or yellow forces as they typically have more men meaning more targets. This added speed of fire warps the barrel of the weapon over time as the constant fire and possible rubbing of projectile on barrel action proves to overheat and soften the metal used. This has sparked the practice of having many soldiers sit within a single fire line and focus on similar targets to mitigate the loss of accuracy.

## Attachments

Optics exist for the weapon to perform at long range often containing an ammunition counter to alert the user of when the weapon will be running out of ammunition. The rounds coming out of the weapon fly at over 6000 fps as they travel down range making them quite useful for longer range combat where other bullets may deviate or turn due to the Coriolis effect or wind deviation. This did though spark the need for more reactive optics such as the ARMSAN which has multiple sensors on it to determine the range of a target, the speed at which its moving and the windage around it, which assists the operator in making longer ranged shots.

AP shedding core allows for the projectile to shed its cuticle on the surface of the target which expands and does extreme damage to unprotected flesh similar to hollow points, the core of the bullet then travels further into the target which negates armor if any exist.
