"This Aeg Rifle set up package is very nice and powerful.This set up comes with a 8.4vdc 1100 Mah. Dboys Ni-Mi Battery. Not the green one you see in the Pic. changed mine out to 9.6Vdc 1600, And found Better Rof. The Mini Type battery is housed in the Crane, 4 postion stock. I swapped out the mtr. to a Matrix Magum hi torque, Now Insane hard hit! Also I have not put mine on a Chrono yet, Its very fast and atleast shots .25 at 300 to 350 feet, Full Auto is a solid stream of bb's! DO NOT EVER SHOT .12 BB'S IN THIS RIFLE OR FATAL DAMAGE TO THIS RIFLE WILL HAPPEN!!! STAY WITHIN .20- .23 -.25- .28g. The package deal is sweet! The Version 3 gear box is tight and semi Quiet, Very High quailty. The kit came with a laser engraved outer barrel(5.56 Nato Etc.) about 6" long for the Flash Hider. The hi-cap mag is 300 count, Nice over all rifle, No trade marks of any kind, except the selector switch. It would be nice to have Trade marks. The All metal rifle is a steal! I give it AAA+++"
