spend more money and get a better gun.. dont make the same mistake i did . my opinion is this was suppose to be jt echo to kingmans mr1 (i dont think it was loud enough) haha its build almost like a spyder but even cheaper(go figure) these guns arnt build to last long cuz mines already broken haha theres not upgrades that are worth paying for for this gun. all in all jt guns =CRAP
