Hey guys this video is my full on performance test of the G&P M4. Overall the G&P m4 is an amazing gun when it comes to performance out of the box. Just make sure you are using a heavier grade bb like a .25 gram or a .28 gram bb and you will have amazing results with this gun. To take the gun a step further downgrade the spring to right under 400 FPS (taking off 30-40 FPS) and you will be able to take this gun onto any field and own! Be advised though do not downgrade the FPS to under 350 fps as the motor and the gearbox was made to cater the 380-430 fps the g&p m120 motor was meant to pull back.
With this all said, BUY THIS GUN!!
