MK109

The **MK109** is a weapon of precise destruction, designed by Rubicon Corporation to participate in the Payload Sniper Rifle Program. This anti-materiel payload rifle is chambered for the formidable 25x59mm HE grenade rounds, and it has proven its capability in defeating light armor and equipment with deadly precision out to a distance of 2 kilometers. Born from the ashes of the failed XMK109 program by Albino Ordinance, the MK109 stands as a testament to Rubicon's commitment to delivering advanced firepower to the battlefield.

## Design

The MK109, initially known as the Objective Sniper Weapon (OSW) and now classified as the Anti-Materiel Payload Rifle (AMPR), is designed primarily for engaging light-armored vehicles and similar targets. Its design borrows the lower receiver from an MK107 but incorporates a new upper receiver chambered in 25mm. Notably, the upper receiver of the MK107 rifles can be readily replaced with an MK107 upper receiver to form a fully functional MK109 rifle, offering exceptional versatility to operators.

The heart of the MK109 lies in its 25x59mm ammunition, originally developed for the cancelled XM305 as part of the Objective Crew Served Weapon program (OCSW). The same versatile round is now harnessed by the MK109, with the option to reconfigure the rifle back to .50 Cal, enabling a seamless transition between firepower options. This transformation is achieved by simply swapping out the 25mm upper receiver for a standard MK107 upper receiver.

The 25x59mm cartridge offers superior power when compared to the SS115 cartridge of the 12.7x99mm SDC caliber (commonly known as the .50 Cal) and even the Dreyfoss round. This enhanced firepower ensures that the MK109 can tackle its designated targets with utmost efficiency.

## Trivia

### General

* The MK109 does exhibit noticeable recoil due to the small amount of propellant used in conjunction with its heavy projectile. This is a result of the limitations imposed by the weapon's muzzle brake. However, when firmly mounted, the rifle's manageable vertical recoil after the first shot makes it an effective and deadly weapon on the battlefield.
* While the first shot of the MK109 is infamous for its high recoil, which kicks vertically, the rifle's straight-line design ensures that recoil is notably lower after the initial shot when the weapon is unmounted. This feature allows operators to regain control quickly, making follow-up shots more manageable.
* In essence, the MK109's ability to swap between 25mm HE grenades and .50 Cal/12.7mm SDC rounds ensures its adaptability to a wide range of missions and target profiles.
* The MK109 has a deliberate and substantial weight of 14.78 kilograms. This weight was intentionally added not only to accommodate the 25mm grenades but also to emphasize the incredible power and force that this payload rifle delivers. The weight serves as a testament to the rifle's capabilities.
* The MK109 is on the cutting edge of innovation. It's currently in the process of developing an airburst round known as the 25x59mm ABPC (Airburst Payload Cartridge). Despite being in the prototype stage, some of these rounds have already been deployed with significant success. This development showcases Rubicon's commitment to staying at the forefront of weapon technology and providing operators with the most advanced tools for the job.
* It stands as a remarkable anti-materiel payload rifle, delivering precision and firepower when and where it is needed most.
* Rubicon Corporation's MK109 is a symbol of innovation in the world of firepower, providing operators with a decisive advantage on the modern battlefield.
