A friend of mine is selling this M4 and I was thinking of buying it. He tells me it's an electric Tokyo Marui full metal rifle. New price worth apparently £450, but I just wanted to find out a little more about it before buying it for £180 second hand, including the scope and handle. If anybody could help me out that'd be great. Big apologies for the low quality pictures, that's all I have unfortuantely. The rifle is the top one on the first picture.
