JG Works Full Metal Gearbox M4 RIS CQB AEG Rifle w/ Metal Outer Barrel

The NEW Full Metal Gearbox JG M4 RIS CQB Rifle is ideal for both indoor and outdoor airsoft games. Featuring a hard-hitting muzzle velocity, carbine length full metal outer barrel, and a precision inner barrel, this AEG can easily take down targets at over 125 feet! JG's newest addition to their line of polymer body M4 AEGs features a complete hand guard rail system, perfect for mounting aftermarket accessories such as optics, lasers, and tactical flashlights with pressure pad! Weaving through confined spaces is made easy by this compact carbine's retractable stock, allowing you to clear rooms with ease! This polymer body carbine comes with the newest JG Version 2 full metal gearbox and can shoot up to 400 feet per second (0.20g BBs), making it a perfect primary weapon for medium to long-range engagements! This M4 AEG performs at the same level as full metal M4s which can cost nearly twice as much, and is perfect for players looking to step up their airsoft game!

Thanks to the full metal quad rails, this M4 RIS serves as a perfect platform to add aftermarket accessories like PEQ boxes, tactical fore grips, flashlights and laser units. This M4 RIS comes fully equipped with a functional charging handle and bolt release, adding to its overall realism. Racking back the charging handle kicks open the dust cover and locks the mock bolt to the rear, allowing you to easily adjust the precision one-piece hop-up chamber. Pressing the bolt release slams the mock bolt home with an authentic sounding "Snap"! The M4 rifle is also equipped with metal sling mounts and retractable M4A1 stock, improving the overall ergonomics of this AEG rifle. The JG M4 RIS features a unique battery storage area, located inside of the included fore grip, with enough room to fit a small type 8.4v battery. This unique battery storage area makes swapping out batteries easy, and keeps the carbine's profile streamlined. Ready to go right out of the box, this JG M4 AEG includes everything you need to start using the rifle on the airsoft field! If you're looking for a hard-hitting M4 RIS AEG that is under $200, then this field-ready airsoft CQB rifle is perfect for you!

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: 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.
