I'd advise you to get a ricochet apache, only around 90 dollars shipped, sleek and low profile, light weight (only weighs 1 pound with batteries) life time warranty, feeds 17-19 BPS (thats plenty fast if its going on a mag), and they look pretty sexy on mags
They are very durable, and shouldn't ever break on you. (and just incase, you have that lifetime warranty
) Also it doesn't use an eye to detect paint, theres a little strip, and whenever a ball passed through it it agitates, so it will agitate every time the gun is fired, and since there is no eye you can use black shelled or dark colored paint in it
