420 FPS A&K Full Metal Airsoft M4A1 Carbine AEG - Full Metal Gearbox

The NEW A&K Full Metal M4A1 Carbine AEG is part of A&K's new line of completely redesigned, performance oriented, metal body AEGs. These NEW A&K AEGs are built to the same performance standards as other top tier airsoft guns costing nearly twice as much. These A&K AEGs not only feature top of the line performance in a durable metal body, but also include everything you will need to start using the rifle! The A&K M4A1 Carbine includes a 9.6v battery, a standard wall charger, a 300rd high capacity metal magazine (feel free to go for the A&K 5000-round M4 AEG Magazine Box), and a metal replacement flash hider! The M4A1 Carbine AEG packs a huge punch in a maneuverable and compact size, shooting consistently over 400 FPS! The M4A1 Carbine AEG is sure to pick off the opposition at extreme distances!

The M4A1 Carbine features a fully adjustable 6 position LE stock, making this AEG more maneuverable and well adapted for close quarters combat. This M4A1 Carbine AEG can also easily hold its own in an outdoor environment. With a precision inner barrel and fully adjustable hop-up, it can easily hit targets beyond 150 feet! The M4A1 Carbine AEG features a full metal upper and lower receiver, a full metal outer barrel, full metal front and rear iron sights, and full metal top rail. The only plastic components on the rifle are the retractable stock, textured hand guard, carrying handle, and the motor grip. The A&K M4A1 Carbine's construction is extremely durable, and has a realistic weight and feel.

The new A&K Full Metal Body M4A1 Carbine has a redesigned and reinforced metal gearbox with a factory installed M120 spring (Airsoft Megastore also carries aftermarket springs like the SHS X-Mod M120 Gearbox Spring), making it one of the hardest hitting stock, metal body AEGs on the market! The full metal gearbox features metal bushings, a metal ball bearing spring guide, a full steel gear set, a high torque motor, and a perfectly sealed cylinder. The A&K M4A1 Carbine also features a full metal hop-up unit as well as a 6.04mm precision inner barrel, providing excellent range and accuracy. The M4A1 Carbine can easily hit targets at over 150 feet away!

Overall, the A&K Full Metal M4A1 Carbine AEG is one of the best metal body M4's on the market, under $250. With solidly constructed full metal externals and a reinforced high performance gearbox, this AEG is able to hold its own against some of its top tier AEG competitors. The A&K M4A1 Carbine AEG provides great accuracy and hard hitting power in a compact size. If you are looking for a top performing full metal AEG, but can't afford the top tier price tag this is definitely the AEG for you!

Ammo type: Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs. For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Battery Charger Recommendation: Although this fully automatic airsoft rifle comes with a standard wall charger to charge the battery, Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery(overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly). Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly,also automatically shut off once the battery is fully charged to avoid overcharged batteries.
