SKU: BI-5181M DBoysOut of stock


440 FPS Airsoft DBoys Full Metal M4 RIS AEG Reinforced AEG Rifle

Our take: The DBoys Full Metal M4 RIS AEG Rifle is the perfect low cost, high performance AEG for both beginner and experienced airsofters alike. This M4 comes stock with reinforced internal components, in addition to a high torque motor to ensure long life at the rifles most optimum performance level. Also coming with a CQB law enforcement style stock, a PEQ battery box, and tactical foregrip, Dboys has done an excellent job in balancing realism and performance with this M4 RIS AEG.

Having such a high performance gearbox, the Dboys M4 also includes a full metal 6.08mm brass inner barrel that allows for clean, crisp, accurate shots to ensure the absolute best performance out on the airsoft field. By removing the included carry handle, you will expose the upper receiver rail system that allows for any standard 20mm mounting optic to be attached to it. Overall this M4 AEG delivers great realism and reliability for a stock gun at a competitive price.

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.
