DBoys M733 Metal Gearbox Polymer Airsoft M4 CQB FPS AEG Rifle - BLACK

There’s no doubt that most players prefer the handling and performance of an AEG than other airsoft gun types. While some can cost an upwards of $200, it’s always a better idea to invest on a base airsoft rifle that you can build from the ground up. The NEW DBoys M733 AEG is the compact, shorter barrel length, CQB variant of the M4 Rifle, with CQB muzzle velocity and 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. It also allows it to shoot below 350 FPS with 0.20g BBs, making it a perfect primary weapon for close quarters combat and indoor fields. 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!

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.

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.
