Our take:  The DBoys M4 CQB-SD with a full metal body (full metal receiver and high performance metal barrel) and a full metal gearbox is a value-minded, high-performance AEG.  It is one of the best choices for an AEG because its lack of compromise between realism and power.  With a full metal body and realistic weight, as well as a full metal gearbox that shoots hard, it is one of the best deals around because of its low price tag. The rifle also comes with a full metal built in RIS system for easy upgrades.  With a muzzle velocity that overpowers even Tokyo Marui AEGs, this M4 CUSTOM CQB-SD is ready to rock and roll.  Also features adjustable hop up, adjustable rear sights, and a rear-retractable 4-point crane stock for extra comfort.  With full Tokyo Marui parts compatibility and many other aftermarket upgrade parts compatibility, this AEG can be easily customized and upgraded.  The rail system further adds onto the upgrade potential of this gun, since you can add an almost endless amount of tactical accessories to it, including flashlights, scopes, and grenade launchers.  The laser in the picture is not included in this custom package.

The all-new enhanced model from DBoys is the model we are shipping here at Airsoft Megastore!  This completely overhauled model features a reinforced full metal gearbox, which keeps its 7mm bearings but features new high-strength polymer-composite bushings for maximum performance!  The full metal barrel has also been improved for maximum shooting accuracy and power.
This fully customized, high-performance AEG package includes:

1. 415 FPS Airsoft DBoys Full Metal Quad Rail M4 CQB-SD AEG Rifle

Operation:  Electric Automatic
Build:  Full Metal Receiver, Barrel, SD-Style Silencer
Firing Modes:  Full-automatic and Semi-automatic, w/ Functional Safety
Muzzle Velocity: 380-415 FPS (w/ 0.20g Bbs)
Gearbox:  Full Metal Version 2
Magazine: 300rd High Capacity (gear wind-up)
Hop-up:  Adjustable
Weight:  8.5 pounds 
Color: BLACK
Ammo type:  Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs

2. G-Force OpSpec Bungee Sling Black [DT203B]

3. AMA 10-Intensity Full Metal 1x40 Red & Green Dot Scope

4. J-Rich 160 Lumen G900 Foregrip LED Flashlight w/ 2 Nav Lights

5. A&K Airsoft 5000rd M4 / M16 AEG High Capacity Box Magazine

Package includes:  Rifle, rechargeable battery, wall charger, instruction manual, 300-round high capacity magazine, 5000 round drum magazine, J-Rich G910 xenon flashlight, premium metal red dot scope, tactical forward grip

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.

"best gun ever "

Great gun

"This gun is very well build, very good RoF even with the stock 8.4, good weight nice solid foundation. very good FPS out of the box, hitting around 405 with .23. The tightbore barrel offers great accuracy, and with the high fps I recommend .25's to keep a 5 inch grouping at even 75 feet. Pro's -High RoF -Great FPS (405 with .23) (415 with .20) - very accurate, Very high quality red/green dot sight - very bright tac light, and sturdy grip. -great price for great gun and top quality attachments, makes this gun terrifying. Con's - mags a little wobbly - single fire select sometime shoots full auto - TAC LIGHT DOES NOT COME WITH BATTERIES get them here 3 cr123a batteries are 5 dollars here, very cheap to retailer stores."

"FAR from the "best gun ever omg". BUT not a BAD gun... These are the pros /cons pros: -Pretty reliable -Decent rate of fire with 8.4v battery, long battery life -OK accuracy -Fully metal -it just gets the job done. -Extending stock is good quality -mine did not come with tac light so no opinion on that. -Grip is low quality hard plastic but firm, works. Cons: -The design seems... off.... it does not feel or look like a real gun to me... -HEAVY! Especially with that damn box mag, lugging this thing around for many hours on end gets tedious...the whole thing just seems clunky, not very cqb orriented. -The red dot it comes with sucks! Mine may have been defective, but the battery started dying in under 3 hours of use every time! If it gets even the tiniest amount of moisture from rain, you pay the consequences! + its fugly -Impossible to get the rail perfectly aligned to 45,90 135, 180 degree angles, many not be an issue to some. -Fps was a consistent 407 with .20bbs. 407 for a "CQB" weapon is a joke, good luck getting into most facilities with that. Not to hard to avoid the chronograph where i go luckily. If power is a plus, then this may be a decent choice. -Good luck getting that fake silencer ( which is metal) off the barrel without some serious working -Mags would not stay in gun,i would be in the middle of firing and they would just drop out... really gotta jam the thing in there for insurance. Summary: Do not get if your young and weak. If you can handle some extra weight and more $upgrades then consider it. Get the version that DOES NOT come with the box mag/ red dot sight - they are junk and are the equivalent to $60 down the drain. Id recommend getting a high quality holographic sight, a flip up front sight ( this gun comes with no front sights -.-) a better sling, possibly a magpul slanted grip (my preference), and of course a slightly weaker spring. Ive since sold mine because i didnt not like the aesthetics at all, it may appeal to others though. 3/5"

The store is amazing. I have found there items that I could not find in other stores which makes it the best. I have made questions and inquires about products and the customer service has responded super fast with accurate answers. All my products have arrived in excellent conditions in spite of other stores. My last product came late because it was rescheduled but that was UPS fault I think. I would like to thank Matthew for his exceptional customer service. Whenever you need help, please try to contact him. My advice, buy in Airsoft Megastore, they have coupons and the widest variety of airsoft products. RandyLoy, USA
I ordered a gun sling a couple weeks ago. Unfortunately, one of the clips broke. After a few email correspondings with a customer service representative named Jun (my emails did not show a last name), AMS sent me a replacement sling for free. I did not even have to send my clip back. AMS is a terrific store and I plan on doing more business with them. They were polite, efficient, and just a pleasure to work with. I would recommend Airsoft Megastore to anyone. mskanwischer, USA
Airsoft Megastore is The Best Airsoft Website Out There (I Think) and i Will Always Be Loyal to AMS and Order Almost All of my Gear From Them. The Customer Service is Also Amazing, Jun my Customer Service Representative Has Helped Me With Anything i Needed Help With, Especially My Order Problem (Had 2 Magazines Missing from Order) and Jun Helped Me With The Problem, and Now The Mags Have Been Shipped To Me. Thank You So Much AMS and Jun. Ethan1214, Saskatchewan, Canada
I love that Airsoft Megastore has videos of most any information you will need to learn and care for your products. I purchased an AEG for my son and in short order, unfortunately, it began grinding after brief use. I emailed for warranty repair with symptoms and with 24 hours (22 to be exact) I received an email explaining possible causes with a video like for tuning the gun. I had the gun working again within 15 minutes, avoiding returning the gun and the mess associated with returns\repairs. Excellence on Sean's part to help out a first time customer of theirs. Highly recommend. bucfanjeff, USA
Everything worked great, shipping was super fast. I am very pleased and won't hesitate to order through airsoft megastore again. rob_riley, USA
