Article number: CA101M13GY
Availability: Out of stock

The Classic Army M4 ARS3-12 AEG is an M4 based platform designed for general purpose usage, with the longer design lending itself to more long range, field type applications. The gun features a monolithic top rail, with more rails on the sides to accommodate for any additional accessories, such as grips, flash lights, and bipods. The gun also features an ergonomic pistol grip, flip up front and rear sights, a retractable crane stock, and a sling adaptor plate. This gun also features unique serial numbers and comes with 2x 300 round metal high capacity magazines.

Internally, the gun has a 9mm bearing gearbox, wire cut steel 21:1 ratio gears, inline mosfet protected trigger contacts, metal spring guide with bearing, 6.03mm tightbore barrel, silver low resistance trigger wiring, and a quick change spring system that allows for fast and easy spring changes without having to go into the gearbox. The wiring utilizes a low heat deans plug and comes with an adapter for tamiya connector batteries. This gun is lipo-ready right out of the box. It will shoot 375-400 fps using 0.20g BBs and 800-900 rpm using a 9.6V battery.
