CYMA "C1" Retractable Battery Storage Stock for M4 / M16 Series Rifles (Color: Coyote Brown)

"This is a very solid stock fits very tight around my elite force m4 cqb buffer tube (can't be moved without hammer) other than that issue it is a very good and sturdy stock. I originally bought this stock because my original elite force crane stock couldn't fit a titan 11.1v nunchuck battery so for anyone who needs a crane stock to fit a titan nunchuck battery this will work.
