Mr. Airsoft is impressed with the King Arms CAA M4A1 CQB AEG (known also as the CAAAD M4S1 AEG) and explains it in this overview video... "This gun is a beast. My brother has had it for about two-and-a-half years with zero issues. It has only been cleaned once, by me, just with silicone oil in the inner barrel (which I will not be using as a cleaning method anymore). This gun has been used in multiple rainstorms, has been dropped in mud and water, and overall has had the crap beat out of it, and yet through all this it still runs like a champ. The only major complaint that I have with this gun is the awful battery storage. Overall, however, I would not hesitate to recommend this gun to a beginner; it is a well-performing sleeper for sure. I hope you enjoy this overview on the gun, let me know if you have any questions or comments.

Thanks for watching."
