Just going to leave these here ?
I traded my we scar for a g36 (which has since been traded on for an army armaments l85a1) and what the bloke called a mk18...turns out it was at all so I sent it to Stuart Kennedy at Airshooters, and he sent it back to me looking all sexy. You can see the comparison pic with the top being how it arrived (with alot of faults...bent barrel, motor in bits, pistol grip coloured in with felt tip, no barrel shims, buckled stock and buffer tube, gears all shredded...list goes on) and the bottom as it is now, with brand new 18:1 gearing, new high torque motor, basically its all new bar the receiver haha!
