"I didnt get this gun fro AMS. but i do have the exact gun.
so here we go. Pros, light weight, super versatile, ambidextrous,nice trade marks, hop-up,turnable sights, not bad FPS. (really good for CQB regulations) and my favorite the manual cocking lever.
Cons, pretty pitiful rate of fire, wobbly stock, no rail for optics,
no this gun is full polymer, which is good for CQB cause you can run with it without getting tired,
my magazine release did break because of the ambidextrous feature, i can work with it you just have to hold the mag and push really hard on the release.
but the stock is extendable, but at the last two settings it gets wobbly,
this thing takes like six AA batteries or if you have a stick battery those with work,
over all really good gun for beginners only.
hope this helped."
