The integrated Quick Spring Change System gives you the option to easily adjust the rifle velocity by adding different springs. Low resistance wiring is used throughout this whole rifle, to greatly increase smooth electrical flow from the battery.
Tgis rifle is very good at the price of around $200. The weight is very close to an actual AR with metal upper, lower, and rail.
Very sturdy very powerful.
My only disappointment is the magazine requires a speed loader. And the battery does not come with the gun
Very good rifle though
