VFC M4 Carbine AEG The M4 by VFC is an excellent replication of the modern M4 infantry rifle. Made in Taiwan, this rifle promises to be of better quality and performance than similar rifles made in China. With a carbine length 16 inch barrel and a telescoping style stock, this rifle is best suited for close quarters to medium 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 300 round high capacity, but there are plenty of replacements available. This model also features laser engraved trademarks and an individualized serial number. The battery compartment is located in the handguard rifle and is very simple to install. Simply pinch down on the delta ring and pull off one of the handguard halfs. Airsoft players love this rifle for its exacting craftsmanship and superior performance. Note: Does not include battery or charger
