This is a great gun. The only thing it needs in my opinion is a koba barrel. And that's not really necessary. I love this gun so much. Its hard hitting, accurate, great feel, as well looks great. The Iron sights on this thing are the best. Although I wanted an actual scope. So I bought a sniper scope, and it WORKS GREAT. For realistic fights and just for a great gun i recommend it. the hopup is located between the trigger guard and magazine. Its great for beginners but I recommend it for any one intermediate and airsoft experts. It fires semi and full auto. But if any1 buys it (which they should). They must be sure not to pull the charging handle back 2 much. my friends did it and it bent the barrel. It took two hours 2 mod things 2 fit and change the barrel.
*Easy to upgrade internals (but if u don't need 2 or don't no how 2 leave it alone or to the experts.)
*Safety underneath the trigger guard
*Easy to use and care for
*Easy to add external parts
*Slightly heavy when fighting long battles easy fixes 2 this problem is 2 GROW A PAIR or buy a sling
*barrel can bend if the charging handle is pulled back 2 much or 2 hard
