EMG CGS Series Colt Licensed M4 Gas Blowback Airsoft Rifle by CYMA (Model: M4 CQB 10.3")

"Pros:

Decent price for GBBR
Compatible with many aftermarket parts for TM
Metal upper/lower reciever, hanguard, outer barrel, and stock tube
Stamped markings are nice

Cons:

Scratches easily (unsure if it's the paint, paint job, or metal quality)
Magazine jammed when firing the first time

Review:

Overall it's a good product for the money, especially with the aftermarket compatibility! The gun looks and functions great out of the box, just as advertised on its store page. Since I don't actually play I can't speak too much about the performance, but I would think this is a decent starter GBBR since the important parts are metal and the plastic parts (front sight, mag release, safety, handle, stock) can be replaced as needed/wanted.

My only gripes are the paint job and magazine. The gun scratches easily and the paint comes off easily. The magazine was the biggest disappointment: it jammed after 8 shots during its first use. I tried to do a quick fix, but ended up taking it apart completely and haven't gotten around to putting it back together; thank goodness I bought a TM gas magazine to use with it (compatible with the gun and works like a charm!). Giving 3 stars because the magazine should be much better quality for a ~$500 gun.
