Our take:  This "high-velocity" version of the DBoys M733 AEG is perfect for airsoft players looking for a little bit more power for outdoor airsoft field settings.  While this airsoft M4 compact carbine features full polymer externals, its high quality, full metal gearbox makes this airsoft gun perfect for entry to mid-level airsoft players that are looking for a field ready airsoft M4.  Firing over 390 FPS, this DBoys compact CQB M4 AEG is perfect for outdoor airsoft fields, falling below the normal legal limit (400 FPS) while providing enough power to hit players at range.  The NEW DBoys M733 AEG is the compact, shorter barrel length, CQB variant of the M4 Rifle, featuring Version 2 compatible parts that make this the airsoft gun of choice for any player.  The first thing you should know is that this AEG is built with a FULL METAL gearbox, which you can build on top of for improved performance. Another notable feature that you should be aware of is its extremely lightweight build.  From the shortened barrel to the retractable LE stock, DBoys outfitted this airsoft M4 with lightweight ABS polymer that reduces its overall weight.  If you’re looking for a field-ready AEG that shoots perfectly for indoor games and comes with everything you need right out of the box, including rechargeable battery and standard wall charger, you can’t go wrong with the DBoys M4 CQB AEG Rifle!

Features:
- Lightweight polymer construction
- 390 FPS muzzle velocity (w/ 0.20g BBs)

- Adjustable front and rear iron sights

- Retractable LE stock w/ sling mount
- Detachable carry handle
- Flat top receiver optics rail
- Battery and charger included
- Compatible with Version 2 parts

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.

Package includes:  Rifle, 300rd hicap magazine, rechargeable 8.4V 1200 mAh mini battery, standard wall charger, cleaning rod, instruction manual

Color:  BLACK

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

"This gun is one of the best guns I've actually had it is ideal for players that are just now getting into airsoft. The gun shoots great and I've had no problem with it at all. Overall I would recommend this to any new player wanting the feel of a great m4!"

Decent for the Price

"I got the gun for my birthday last December. The gun only lasted into February. I took the gun apart, cleaned the barrel, checked out the hop-up unit, and even rebuilt the gearbox with a friend. Only then would the gun work like it did. Pros: Decent rate of fire stock, lightweight, decently accurate, shorter barrel for CQB. Cons: Cheap plastics, no rail system to use w/o wiring to the rear. Long story short, if I were you, I would save my money to get the Lancer Tactical Polymer PDW."

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
