On a budget? Team Blacksheep is here to help as they made a comparison of two budget M4 AEGs from Echo1 USA --- the Genesis and Bravo M4 RIS AEGs... "It depends on what you are going to be doing with the gun and in your airsoft campaign. If you are going to buy a gun to play once or twice and not upgrade or modify it then the Bravo M4 RIS will be what you want. The RIS is ok but plastic.

If you want to get into airsoft and play many times during the sueason and upgrade later on then the Genesis M4 will be what you want to get. Yes it costs a little more but get that difference in price in the parts installed and ready for you. The MadBull bucking, 8mm steel bearings and the super gearbox that can be upgraded with the crazy parts you want to use."
