DBoys M4 RIS Metal Gearbox MK18 CQB FPS Airsoft AEG Rifle - BLACK

If you’re looking for an airsoft gun with a FULL METAL gearbox compatible with aftermarket parts, then there’s no better choice to go with the DBoys MK18 Airsoft Rifle. Based on the rifle system used by the U.S. Navy, this CQB-velocity AEG shoots between 350 and 360 FPS (w/ 0.20g BBs), but you can easily modify the internal parts with upgraded springs, pistons and gear sets. This airsoft guns features lightweight external parts that makes it ideal for all players. Polymer upper and lower receivers significantly reduces player fatigue. A retractable crane stock offers custom shouldering and comfortable cheek weld. And a CQB-length quad rail system (which can be replaced with an aftermarket full metal RIS) lets you mount accessories like tactical lights and lasers. In addition to built-in features, this DBoys MK18 comes with a removable tactical foregrip for ease of handling. This DBoys MK18 AEG is perfect for any player looking for a field-ready airsoft gun that shoots at a lower muzzle velocity for indoor games and comes with everything you need right out of the box, including 8.4V nunchuck battery and standard wall charger!

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
