Description:
The Guns Modify EVO stainless steel magazine output valve is designed to be more robust and ideal to take the more extreme rigors of green gas usage. The valve not only works with the Hi-Capa series magazines, but you can also use this upgrade part with the M4 MWS magazines as well! This added strength will greatly improve consistency and efficiency.
