JG Bar 10 Upgraded Faulty

I have my JG Bar 10, I've skirmished it 3 times and started to upgrade it when I hit a few issues, it has a maple leaf bucking and an action army 430mm barrel in, it now slam fires and I don't have the time to fix it, the RIF I have also sprayed myself black, it would make a good boneyard project. the RIF will come with a 3-9x40mm scope as well as 4 mags plus a rifle bag
