I love this gun!!! It got great acuracy and killer speed. I've been playin' with it for 6 month now and done extreamly well with the stock barrel system. There is a must on havein' a rev.
I've only had 2 major problems with the gun. the regulator is not of the best calibur so upgrade to another reg. Second the micro line is too easy to be blown so the steal bread is better.
Out of the box this gun for 400 bucks is quite a good deal. Its torniment ready for those who can't pull the harder triggers like on the stock mag and cockers. I find that the upgrades aren't manditory but the gun works alot nicer with them. As for similar guns the tribal is like a compleate replica of the bush just with minor changes in barrel and regulators. I seriously reccommend this to those who are lookin for and electric gun but aren't willing to pay the price of an angel.
