I did a lot of research looking into getting my first aeg and ended up purchasing this in the SA-FX01 flex model. I was not disappointed and would highly recommendthis to anyone looking to get a SMG. Externally the rifle is extremely well made. Thick durable plastic much like a g&g for most of the construction. Fiberglass infused polymer body looks and feels like quality construction. The rifle has a very good weight and feels solid and tight. Over all what attracted me to Specna Arms was the emphasis on quality and durability. Again on receiving and playing with the rifle I was not disappointed. This is a high quality and a very affordable replica packed with everything you need to go out and have a great time!
