Carol Grillo checks out this Tec-9 AEG, more known as the Echo1 USA GAT AEG for this video review... "This Tec-9 AEG is a great airsoft gun. It is very small and compact for CQB fields. It is great to use, easy and is a high quality Echo1 brand. The battery enters the front. I recommend this weapon if you want a small and reliable AEG."
