This YouTube Unboxing Preview Video focuses on two AR M4 styled AEG Airsoft Rifles. The G&G CM16 Rifles are all pretty much the same other than the barrel lengths and come in the following versions, the CM16 SRS, CM16 SRL and CM16 SRXL. I also showcase the Umarex HK M27 which is distributed by Umarex but made by VFC which is knwo for their high quality products. I will be following up this Preview Unboxing Video with individual more detailed Review videos for each AEG AR M4 rifle.
