VFC M4ES 200R Rifle AEG The M4ES 200R by VFC is an excellent replication of the modern M16 rifle. Made in Taiwan, this rifle promises to be of better quality and performance than similar rifles made in China. With a full length 20 inch barrel and a full length stock, this rifle is best suited for medium to long distance outdoors engagements. With realism and functionality in mind, VFC built this rifle with a full articulating charging handle that pulls back a fake chrome bolt to expose the hop-up adjustment wheel. When you're done adjusting, just push the bolt release and the chrome is released back to its forward position. The upper receiver, lower receiver, barrel assembly, and magazine are a high quality aluminum alloy and the rest of the furniture is durable fiberglass and nylon as needed. The gun comes factory upgraded with hardened steel gears, hardened piston, high tension spring, 8mm bearings, and a high torque motor. The included magazine is VFC's 118 round mid capacity, but there are plenty of high capacity replacements available. This model also features laser engraved trademarks and an individualized serial number. The battery compartment is located in the stock of the rifle and is very simple to install. Simply open the door located on the butt plate and connect the tamiya plugs and close. This rifle is set with a Small Tamiya plug and not a large one. If you want to use a large style battery you must either get a small to large adapter or rewire it for a large plug. Airsoft players love this rifle for its exacting craftsmanship and superior performance. Note: Does not include battery or charger
