A Bullpup Break Barrel rifle stock. THIS IS NO GUN, ONLY A ACCESSORY!you need:17x DIN 912 M4x25 Screw8x DIN 912 M4x16 Screw4x M4 Hexnut2,5mm Steelrods (Weldingrods work perfectly)Print everything with your normal print settings, maybe a little bit more wall & infill (100% is definitly not needed, i did 3 Walls and 40%)Take a 2,5mm Drill for the holes next to the screw holes connecting front and backpart and drill in the small hole. In this hole is the Steelrod pressed. Take about 2-3cm of the rod. This is to align the pieces and to give extra strength.Connect the front and back part of each side with 2 screws and 2 hexnuts. Take sandingpaper and sand the linkage down, so it runs smooth in the channel. The same with the trigger.Take one sidepiece, lay in the Rifle and take one of the original Riflestock-Sidescrew and screw the part together with the rifle. now put in the trigger and take a file and shorten the trigger linkage till it has the perfect lenght fitting between the rifle trigger and the 3D printed one. this step is necessery. screw in the original middle screw in the back of the rifle a few turns but dont screw it all the way. now put on the other side and screw all screws in. now take a small flatscrewdriver and turn the original middle screw till you think its fit.now screw on the scope mount. (the hole points back and works as a kind of rear/front sight).Now Screw on the front grip.Have fun and fgc
