It looks like the metal housing at the back of the gearbox extends up quite a way inside the buffer tube it’s certainly not empty down to the receiver. There’s only a few inches between the back of the gearbox and the end of the buffer tube. Although I haven’t been able to put the new stock on yet anyway - can’t get the locking pin to travel down far enough.Really? I can fit a 7.4V 1300mAh LiPo in a standard M4 tube....
