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!

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."

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
