"This M4 is the combat machine killer. The body is a sturdy nylon-reinforced polymer and I have never had problems with it through multiple skirmishes and backyard games. The internals are on-par for this price point and are more than acceptable. If things break, they are easy to modify. The pre-installed MOSFET works well, and the micro-switch significantly improves trigger response, making this replica feel like a much more expensive rifle. The M203 has minor problems with it's firing pin being too soft, but there are solutions to this and most grenades still work with it. The hop-up and barrel are poor, but most are at this price-point and a simple investment of 20-30 dollars per piece will instantly make this gun solid and it will compete with the best. Overall good purchase.

Sturdy body with solid weight
Decent gearbox and internal components
Great trigger response
Easy to open and modify
Accurate for the price

M203 is picky with grenades due to a soft firing pin
Hop-up is budget, and can have trouble with heavy weight bbs and can be damaged easily.
Sluggish RPS

"Best stock aeg I have ever purchased for $100 bucks.
This gun has a stock mosfet and micro trigger switch that comes with it and really makes all the difference. Every shot is crisp and consistent. There is absolutely no gear whine and just sounds so much nicer than any of my friends.

Some pros:
-mosfet (so you can use lipos)
-micro trigger (crisp responsive trigger)
-quick change spring (makes opening the box 100 times easier)
-under $150!!!
-metal outer barrel
-metal trigger, mag release, bolt catch
-the stock piston has metal teeth
-decent gears with an abs plastic delayer chip
-overall lightweight construction (plus for me)
-upper/lower reciever and pistol grip are a nice feeling durable plastic

Some cons:
-the buffer tube, stock, and hand guard are cheap crappy plastic, I replaced all those parts

If your looking for a new build platform, or just getting your first gun you will NOT regret buying this aeg
