I have an Echo1 DSR, includes a cqb and long receiver for both types of gameplay. It shoots about 400 fps and has a very nice rate of fire, its about a year old and slightly used. comes with 4 mags, sometimes one of them doesnt feed properly(just needs to be cleaned). Takes a small type battery. has a bipod on it also. great gun for the price. Asking $100 obo or partial trade. text at 602-214-6556 or pm
