Caber's Thoughts:

The Specna Flex and Core series of AEG M4's is quickly becoming the dominant rifle for newer players. Their internals are amazing and the price is hard to beat. One of the major difference between the Flex and other entry level AEG's is Specna doesn't use metal sights and buffer tubes which allows for a lower cost.
