CMMG Bravo Echo Trip

grabcad

This model was designed by me based off of the CMMG Bravo 22lr conversion kit for an AR15. This model WILL NOT convert your gun into a machine gun nor will it trip the auto sear on a full auto lower, this model WILL trip the trigger block on the Fostech Echo Sport allowing function of the conversion kit with a lower that has the Echo Sport trigger installed. This may work on the other Echo triggers however I am only able to test it on the Echo Sport. Minor fitment may be required in order to achieve complete functionality and a proper fit. The model version I printed was a little too big and I just shaved the outside down until it fit in the receiver. The length of the model that interacts with the trigger block was correct, requiring no adjustment after printing. One of the ears will end up breaking off during assembly, I wanted to have it clip on but it isn't necessary functionality wise.Designed using Autodesk Inventor 2018 ProfessionalModel STLs are in metric
