"This gun is just simply fantastic. I've put about 8 high-caps through it and it's shooting great.

I bought this after owning an Echo1 Stag-arms M16 for about three years, and this thing just makes me smile every time I shoot it.

The function is like the Icing on the cake, this gun shoots maybe 390 fps, Give it maybe an m120 spring and you'll be shooting about 400-420 fps. Just make sure the motor is up to it, I haven't owned the gun for too long but maybe you would have to change the motor.

Overall a fantastic gun; I would recommend this gun to anyone looking for a high quality AR platform that has a longer barrel, with that fixed-stock.

"This is my first AEG review, but I am EXTREMELY pleased overall with this gun. I have been a fan of G&G since I started playing airsoft This gun holds up my expectations very well.

-Sturdy build with high quality CNC aluminum and nylon fiber.
-One of the most accurate guns I've ever fielded (partially because it comes STOCK with a 6.03 mm inner barrel).
-Dead reliable (first game I used it in, I put no less than 3000 rounds through it. I only had misfeeds a couple of times. This was found to be due to a poor magazine lip though).
-Some quirky features such as a spring release for after prolonged play, or the affixed receiver pins for takedown/cleaning.
-Fuse included
-Unlike some other reviews say, the hopup chamber WILL stay open if you pull the bolt cover back and hold it, then pull the external release outward. Simply press it again to close it.

-Stock hopup is sub-par at best. (Easy fix with an aftermarket unit).
-Hard rubber pistol grip gave me fatigue after hours of play. (Easy fix with cling camo or electrical tape).
-Blowback creates a lot of noise.

"I have owned this gun for over 2 years. It is still shooting like the day I got it- fantastic. I have used many different mags in it- it can be picky with the full metal receiver, but I have found both hi-caps and mid-caps that work well. It is very accurate- you can use it for a sniper rifle with the benefit of full auto firing, and high capacity. You can us it for a squad support weapon with a box mag, or severl of the G&G 450 round hi-cap mags. Mine has consistently shot around 390-400 fps with .25 bb's. The externals are great, and durable. The internals are great and durable. The only thing I have changed is the pistol handgrip (put a magpul MOE one on as it was more comfortable in my hand). I own about 8 good airsoft guns, but when we are playing a serious game, a MILSIM event, or a game where I want to reach out and touch people that think they are far enough away- I reach for this G&G Top Tech M16. I have also mounted a 4X vietnam era type scope on it and sniped people that thought they were a safe distance away. I have measured off distance to see the length it will shoot accuratly (man size target- not a small ring), and it will reach 175-190 ft depending on wind interfering. (no exaggeration). Plus- I got this with a 20% off coupon so I paid about $240 then for the gun- a steal in today's market. I hope this review helps anyone who is thinking about this gun. It looks plain versus the hi-tec, railed, add on guns all over the websites- but there is no substitute for quality build and performance when you are on the field.
