BSSR-180 "Bass"

The BSSR-180 Battlesuit Standard Sniper Rifle, Bass Variant, is a magazine-fed, 25x197mm, semi-automatic anti-materiel sniper system. It is used by the Luminarian Ground Forces and despite its designation as an anti-materiel rifle, it is also used as an anti-air and anti-vehicle system.

In Year 9 of the Great War, the BSSR-180 entered service as a battalion-level weapon, issued to dedicated sniper squads. It is currently the standard long-range sniper weapon of the Luminarian Ground Forces.

Background
The BSSR-180, is a 4th generation sniper system designed for use with battlesuits. The BSSR-180 was designed by Valrius Land Systems, as part of the Luminarian Ground Forces need for an updated sniper system that was capable of engaging hardened targets. It called for a weapon that could take down battlesuits with a single shot and could penetrate armor at a rate the BSR-127 couldn't. The weapon also needed to use the newly developed 25x197 ammunition that was superior to the older 14.5x114mm ammunition used by the LBSR-800.

The BSSR-180 was essentially a stripped-down VAC-259 "Flux" Autocannon, commonly mounted on the Riptide IFV but designed to be battlesuit portable. The weight and size of the BSSR-180 is considered to be extremely unwieldy for even battlesuits, and as such rarely seen on the battlefield. As such, the BSSR-180 is a battalion-level weapon, utilized by specialized teams as the BSR-127 had enough range to fulfill the role of a sniper rifle and firepower for most situations.

During the Zaretian Theatre, BSSR-180s would be used by dedicated sniper teams. It's penetrative power utilized to take out targets behind hardened structures as well as providing limited Anti-Air fire against VTOLs. On occasions, sniper teams would also use the penetrative capabilities of the BSSR-180 to engage Zaretian MBTs. The use of FAPDS rounds would further improve the lethality and penetrative capabilities of the BSSR-180.

Bass Variant
The current variant of the BSSR-180, codenamed Bass, incorporates many 5th generation features, such as a next-generation integrated ballistics computer, recoil dampener, an inbuilt rangefinder, integrated heavy barrel suppressor, adjustable all-terrain/all-pose capable bipod.

Design
The BSSR-180 features 4 accessory rails on all 4 sides. This allows for all current 3rd generation and above weapon attachments to fit the BSSR-180. The barrel and stock are also replaceable to allow for more versatility depending on the situation.

The BSSR-180, using the standard APFSDS-T 25x197mm round can achieve a 29.3cm penetration rate against standard 3rd-generation vehicle armor, and a 16.72cm penetration rate against standard 4th generation vehicle active armor if firing at full power. Utilizing FAPDS rounds can further improve penetration, with up to 35.4cm penetration against standard 3rd-generation vehicle armor, and a 20.25cm penetration rate against standard 4th generation vehicle active armor.

Overpressure from firing the weapon at full-power in an enclosed space can cause internal organs to rupture, and operators of the weapon must be armored and sealed to withstand the effects.
