E&C Airsoft MK12 Reinforced Airsoft AEG Rifle (Model: MOD 1)

"Hey all so this is my first time buying a guy in 12 years and at the time there were no reviews on this so i was nervous but it arrived today. So let me just tell you all about this gun.
Pros
The aim on it is simply perfect. Ive had alot of airsoft guns in the past but none have been as dead on as this one. It has perfect accuracy and i havent even put a red dot or anything on it yet.
The weight also feels really amazing. Its nice and sturdy and is full metal and it is a beautiful gun all around.
The magazine fits perfectly in it and all the moveable parts are sturdy and none move around unless i want them to.
Tbh everything about this gun is absolutely perfect. The only issue i had was trying to figure out where the battery goes in the gun(battery sold seperate) but after watching a youtube video i learned that most full metal ars have swapped to having their batteries in the back stock of the gun. So after playing with it i found it and its super easy. Only thing im uncertain of is if the stock is adjustable. It says it is but ive pulled the handle all types of ways with the release switch and nothing. Not that it matters since its perfect size for me but still just something id like to know. But other than my own issues this rifle is a masterpiece and i highly recommend it.
