Bought this as a boneyard gun. Turns out the gearbox casing was cracked out of the box. I have replaced it with an e&c one. The gun now runs just fine but the trigger pull is a little hard as the trigger isnt quite right for the new casing. this could easily be improved by filing a small amount off the back of the trigger. The gun comes with 2 midcaps and 2 mlok rail sections. one of the rail sections is missing a screw as the sellere mispacked it but that can easily be replaced. Price includes fees and postage.
