"I purchased This M4/16 last week and arrived in great package and box up well,Keep in my this is my 1st time buying an Air Soft GBB Rifle. I finally got a chance to test fire it and was able to hit 2" Target from 100 feet 4 out of six shots but I change the rear and front sights to my SiG MPX metal sights since the original sights were not to my like and rear one was cheap plastic and felt it would break if I flip from far shot to near shot. It outer casing seem like cheap plastic but once you hold it and get used to it is all good quality, only con is the metal magazine it's not the easiest to load and only holds 50 BB's, magazines are $45 a piece compare toy sons AEG Rifle Magazines are way cheaper. So far this compares to my real M4 bit with less kicked.

"The CQB-R variant is my first ever GBBR, and I love it. It’s super cheap and gets the job done. It fires way over 350 FPS (my cqb arena’s limit) at around 380-390 for the first 10 or so shoes after a fresh refill of green gas, but dips down to 330 after that. However the upper, lower, pistol grip, and stock are all plastic, but the buffer tube and RIS are metal.
