The M4 S-System Carbine AEG has great range despite its compact size, shooting accurately over 100 feet! The M4 S-System Carbine AEG can easily pick off the opposition at long distances, keeping you out of the opposition's range!

The M4 S-System Carbine features a fully adjustable 6 position tactical LE stock, making this AEG more maneuverable and well adapted for close quarters combat. This M4 S-System 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 100 feet! The M4 S-System Carbine AEG features a high-quality impact-resistant polymer upper and lower receiver, a unique S-System hand guard rail system, a full metal outer barrel, and metal front and rear flip-up iron sights. The unique S-System hand guard makes loading batteries a breeze, with two spring loaded hand guard release buttons. The S-System hand guard also features lightweight anodized aluminum rails, providing plenty of space for attaching a variety of tactical accessories and upgrades. The polymer components on the rifle include the retractable stock, hand guard, and the motor grip. The A&K M4 S-System Carbine's construction is extremely durable, and has an ergonomic feel and realistic weight.

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.

Great gun
29/01/13
By: Chase

"This is a great gun i just got it today and it shoots great right out of the box. Most people would think that its a cqb gun but it actually works great in an outdoor field. It comes with a metal tip to replace the plastic one but the plastic one is a pain to get off so i just broke it in half. Pros: Greatly Balanced, Lots of rail space, good fire rate, and feels good in your hands Cons: Would get heavy after a while Grade: Beginners-Intermediate Upgrade Potential: Immense Rate: 5 star"

Freakin' Boss
22/09/12
By: Brandon

"This gun is amazing. It shoots far, it's nice and heavy, and has a great feel. Plus, it looks BOSS with my attachments on it. Only two problems: 1) They give you a replacement metal flash-hider, but the plastic one that's on the gun when you get it is a bitch to get off. Like two hours of work, but it was worth it. 2) The magazine that the gun comes with is . . . well . . . crap. It only feeds about half the ammo before you have to wind it again (good thing I'm getting more mags anyway). All in all, it's a great gun and is totally worth the money."

The gun for beginners
27/02/12
By: Ryland Van Pelt

"This was my first AEG way back in the day and i still own it... Ive since upgraded but i must say that this is still a go to gun for me. It takes upgrades well and its amazing right out of the box anyways. This gun is made for beginners and built to last until you arent a beginner anymore. I recommend this gun to all new airsofters looking to get serious without robbing a bank. Amazing gun!"

"Worth every penny. Good feel, and easy battery install (not like most M4 models). Pretty heavy for a non-metal gun (plus for me)."

"I've had this gun for quite some time (about 2 years) and I have to say it is a great beginner gun. Over time there had been some problems with the gun, but that was from some abuse in the field and natural wear-and-tear. I'm currently upgrading the internals including a new gear box, pistons, a tight bore barrel, as well as the pistol grip and stock. I have put a damn fine red/green dot on and the gun works great in both cqb and field. With the price, you can't go wrong with this gun. Pros: -rails -fps -weight (not too heavy, not too light) -decent rof Cons: -wears down somewhat easily over time -both the stock and pistol grip have some wobble"

Eine Rezension von Grant
22/01/11
By: Grant

"I honestly love this gun! It has a nice rate of fire and it is HEAVY! 8.5 pounds, the same weight as the training rifle that the marines use. I had mine for about a month and then the tabs at rhe rear of the upper reciver broke... I'm not really shure how that happened, so I got confused... Airsoftmegastore is working on replacing it now though. Thanks Airsoftmegastore! One final thing, it is pretty front heavy..."

very hard to fix internally
19/03/13
By: Benjamin

"looked, felt, and shot great until the air nozzle broke which I thought was no biggie cus they're pretty easy to replace. Ordered a g&g combat machine replacement air nozzle and opened up the gear box to replace the broken nozzle, only to find that it wouldn't fit. I then proceeded to change out the piston head so the nozzle would fit, then found that somehow the nozzle no longer made contact with the hop up unit, which is made unique for this gun. I replaced the hop up unit with a new one which still didn't fix it so I gave up and bought a g&g combat machine m4 raider which i should have done in the first place. the A&K is a good gun as long as nothing goes wrong"

"Seriously guys, JG makes the better M4. Not only is the quality of JG better, it has an M4 with the MOSFET chip available (kinda expensive tho.)"
