i found a great model of the MP5K ris on thingiverse but unfortunately it just gives error 404. i found the original source, a brilliantly made exploded 3d model of a JG mp5k (https://grabcad.com/library/stinger-r36-airsoft-gun)

i have isolated the RIS guard parts and uploaded here as i saw a few comments asking for it. i have not yet printed it but will do and will update when ive done it. if anyone else beats me to it please message and let me know

PRINTED TODAY...ITS BAD Do not print this yet. it will fit the rif and doesnt look to bad but it has very weak areas and the rail sizes are totally wrong. you cant fit things too it haha i am now modifying the model, will print it up and show pics aswell as update files
