The PARTISAN-9 is a firearm inspired by the FGC-9. It uses an internal recoil system that enables it to use a low profile upper receiver and removes the need for the fixed buffer tube. It has a folding stock with a built in separate buffer weight and a bolt that partially reciprocates into the stock when firing. The upper uses a new type of front lug that locks into the lower and solves the issue with broken front lugs that the previous guns in this family have suffered from since the Shuty AP9. It has a hollow charging handle with a magnetic retaining system and a M3 all-thread rod that goes through the whole upper assembly. From the barrel retainer to the endcap, clamping the whole upper assembly together for increased durability. The barrel uses an anti-rotation system that prevents the barrel from rotating when installing and removing a suppressor. Special thanks to Ivan the Troll, JStark1809 and 3socksandcrocs for the work on the MK2 which is the firearmthat the PARTISAN-9 was inspired by, as well as the beta testers of the PARTISAN-9. In particular Guerillafighterwho printed all prototype pieces instantly without question and helped with instant feedback as well asBroletariat and Potadoze who was the first beta testers to fire the PARTISAN-9. Huge thanks to the designers whose creations inspired and influenced the PARTISAN-9, in particular Derwoodfor coming up with the Shuty AP9 design, which the FGC-9 MkI and FGC-9 MkII core mechanisms are based on.As well as to Noketchup, who designed the FGC-22 which was a big part of the inspiration which lead to the PARTISAN-9. Massive thanks to Cskeju for recognizing electro chemical machining as a way to make rifled barrels long before 3D printing was a thing for the common man, and to Jeffrod and Ivan the Troll for developing this methodfurther. This is the foundation that makes all of this possible .Credits to Mussy for the “HD Light Stock” which the PARTISAN-9 side folding stock is based on.
