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.

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.

hey

"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."

Decent

"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"

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
