Echo 1 M4 RIS AEG (JP-12)
The M4 RIS AEG by Echo 1 is a part of a family of rifles modeled off the original M4. This model features high fps, 16 inch barrel, and a multi-position telescoping stock making it perfect for medium to long distance target engagement. The upper receiver, lower receiver, motor grip, and stock are reinforced plastic and the RIS unit, barrel assembly, and magazine are metal. The included magazine holds 300 rounds and there are plenty of replacements available. The battery is located inside an AN/PEQ box and although it is a large style battery it has 4/5 Sub-C cells and a small tamiya connector instead of a large one. The included battery is a NiCd type. For optimal performance it is recommended to get a charger with a discharge function.
