Nerf Modulus MKII UC kit

I decided to remix this so instead of creating a new part to mount on the existing cocking sleeve, I should just design two cocking arms that bolt directly to the front grip and breach sled. You just need to get two screws for the front grip or redesign the arms holes and front grip holes for the screw of your type. The screw I used on hand was a M4-0.7x8 screws. You can use the existing sled screws for the inner part, just thread them in through your printed arms. It took me three tries to get the arms at a correct length and it's almost perfect for me. Have fun,happy modding. BTW, the original Barrel file and front grip files are perfect. Kudos to the original designer.
