Pisang Airsoft is impressed with the performance of the G&G CM16 SRS 2.0 AEG out of the box, which is always a plus point for us since we'd rather have a good performer right out of the box than spend more on upgrades... "Dominating with an INSANE out-of-the-box airsoft gun. The G&G CM16 SRS 2.0 is an excellent out-of-the-box airsoft gun. This gun shoots straight lines without any upgrade. Literally, insane!"
