Brief review of the M4A1, a product of Tokyo Marui. This gun is an electric airsoft gun. Main new features of this gun are "Recoil shock", "Auto-loading-stop lever". This gun also is made with many metal parts. This is the first AEG for me, and I don't know well about rifles, so please just have fun. I hope this can give you nice information.
Please tell me if there's something you'd like to know about this gun. I maybe will respond to your questions.
