Review:
This is a great beginner gun. Ive owned it fora few months now and i play open play at a local field. I am not very great but it still does the job. You can shoot this gun very very fast and it rarely jams. I havent once chopped a ball in this gun but ive gotten balls stucka nd sometimes my gun did not recock i think it is from the cold weather. Very fast and clean sleek design.
Conclusion:
Very good gun. I love it. Does everythign i need it to very fast worth the money and not cheaply made.
