RP-47 Zuki

The RP-47 Zuki also nicknamed the Gargoyle is probably one of the most oldest Assault Rifles developed by the Passivarian Republic and then later by the Quantonian Empire, in fact it was the first ever fully automatic magazine fed non barrel rotary weapon to have been invented, it was first designed on the 12/04/1870 (Pre-War) and was first produced on the 04/05/1876 (Pre-War). The RP-47 first generation functioned with air compressed mechanisms which made its internals work in a clockwork fashion giving it excellent reliability and little time to jam, such weapon was a revolutionary piece of equipment which paved the way for future fully automatic weapons.
The RP-47 is easily identifable by its straight magazine infront the trigger, it has an adjustable stock and 3 gas pressure pistons along the side which if not careful can end up someone losing a finger if not cared with properly, At the end underneath the barrel is an emergency pressure release valve which trips if too much heat and/or pressure builds up inside the weapon, which leads on to another fact of the weapon being the first to implement safety measures.
The RP-47 also comes with an attachment rail on the top to allow options for scopes.
On the year of 23/04/2025 (Post-War) the Quantonian Empire Government wanted to revise the RP-47 and upgrade it to contemporary standards, so they implemented an upgraded design, this design was first developed on the 04/05/2025 (Post-War).
The upgraded RP-47 had an electronic motor to increase the power of the clockwork mechanisms, these mechanisms also came with a static charger to keep the weapon fully charged and never running out of power, such upgrade came with a built in faraday cage making it immune to Electro Magnetic Pulses.
The gas pressure pistons on the side are encased in a protective container to prevent injuries occuring to users, the case also has a cocking handle in case the gas pressure mechanisms need to reset.
The upgraded RP-47 still has the emergency pressure release system, but due to the upgrades it has rarely been activated.
The RP-47 is also a loud gun, when firing not does it have the gun fire it also has the loud chugging and clicking of the internals, which also gives the weapon a record of loudest gun system.
The RP-47 fires at an impressive 800 rounds a minute with the ability to handle 40 caliber rounds whilst mainting a lightweight full functionality. The RP-47 is still used to this day by general infantry of the Quantonian Empire, but not as often as its more of a specialty weapon rather than general use.
