i found the star crane stock is a little better setup as it opens up from the rear and allows you to slide the battery in from there, where as the ca stock opens from the front, so you must remove the stock completlty to charge the battery and i found it is a hassel to get in out of the tube (the battery) the buffer tube is pretty narrow.
however if you get those battries specifically designed for the stock held in the triangle shape via the hard mould would solve the problem.
but i too love the s-system cqb look. very unique and beefy looking. almost looks better than mine dan.... ALMOST... lol
