Tokyo Marui has released it’s own RIS version of the popular M4A1 rifle. The Marui AEG offering has a mock laser mounted on top concealing a small battery. It has adjustable features to accommodate differing fighting styles; the tactical vertical grip can be moved or removed to allow the attachment of other accessories on the rail and the carrying handle can be completely removed.  Metal parts include barrel assembly, fully adjustable front/rear sights, magazine, trigger, handle/upper receiver, and T charging handle. The inside construction of the rail is also metal, giving the rifle more weight up front compared to a stock M4A1. For authenticity's sake, the dust cover springs open when you pull the charging handle - just like on the real steel! A metal flash hider screws off for attachment of a standard 14mm counter clockwise threaded silencer. The composite rear stock is extendable.
