Had to put it in a chassis so the kid could shoot it with a smaller length of pull. Worked well had to cut the buffer tube down to make it as small as possible. You can see the difference sitting next to a Krg bravo. It’s the MDT lss xl. I am going to go to a vertical grip for his small hands. He is 4 so needs everything small. Will be nice once he gets the hang of this I can just swap in a bigger caliber in the chassis.
