JG M4 RIS CQB Full Metal Gearbox Airsoft AEG Rifle

SKU: JG-F6617 JGOut of stock


JG M4 RIS CQB Full Metal Gearbox Airsoft AEG Rifle

Our take: It's finally back, hot off the production line! The highly-anticipated JG Enhanced M4 RIS CQB w/ crane stock (pre-wired from the factory for crane stock battery storage/access) is FINALLY back, and Airsoft Megastore is the first and only Airsoft retailer in the nation to carry it. The M4 RIS features a coveted and versatile design, sporting a full length AR barrel with a full metal integrated rail system [RIS] AND a retractable crane stock for battery storage for a fuller battery compatibility list (8.4v / 9.6v crane stock battery).

It is one of the best choices for an AEG and also is one of the best deals around because of its low price tag that includes the full metal rail system AND a retractable crane stock. With a muzzle velocity that overpowers even Tokyo Marui AEGs and its JG full metal gearbox & super high-torque motor set-up, this M4 RIS is ready to rock and roll.

Also, the JG M4 RIS CQB features adjustable hop up, an adjustable rear sight, and of course, the retractable 4-point CQB crane stock for extra comfort. With full Tokyo Marui parts compatibility and many other aftermarket upgrade parts compatibility, this AEG can be easily customized and upgraded. The rail system further adds onto the upgrade potential of this gun, since you can add an almost endless amount of tactical accessories to it, including flashlights, scopes, lasers, and grenade launchers.

Newest Production Run Model - Airsoft Megastore Exclusive

This year, JG has improved and rebuilt this AEG from the ground up to be a world-class Airsoft Rifle that holds a perfect balance performance and value.

- Barrel: The gun comes pre-upgraded from the factory with a precision manufactured tight-bore high performance barrel that delivers increased muzzle velocity and accuracy, while eliminating jam-causing barrel manufacturing imperfections.

- Internals: JG has reworked more than 90% of internal components, making many revisions that add to performance while drastically reducing wear and tear on KEY gearbox components.

- Gearbox: The full metal gearbox features a polycarbonate piston, STANDARD FROM THE FACTORY, a practice typically reserved only for more expensive ultra high-performance Airsoft guns; a high performance gear set also aids in making the operation of the gearbox smooth and synchronized.

- Motor: A newly re-designed JG-M3000 ultra high-torque motor is the perfect finishing touch, working harmoniously with the gearbox of fire; the gearbox works harmoniously with the newest version of JG's ultra high-torque motor to deliver OVER 850 ROUNDS PER MINUTE on full auto at OVER 400 FPS.

- The Complete Package: JG continues to innovate year over year, and the results are pretty spectacular. What you get is a high-performance Airsoft gun with top-notch power, accuracy, and reliability

- AMS Exclusive: Because of the significant purchasing power we hold, we often gain exclusive access to the newest models in Airsoft first. In typical AMS fashion, we bring it to our customers AT THE LOWEST pricing possible. At this time, JG's hot newest line of Airsoft AEGs are available exclusively at Airsoft Megastore.

QUALITY ASSURANCE: Through numerous factory visits, we are able to confirm that JG tests EACH and EVERY single AEG that they ship out by putting each unit through a rigorous 16-point inspection, which ends with a Q.C. agent shooting no less than 450 rounds from the rifle to ensure quality before exiting the factory (hence sometimes buyers may find a BB or two left in their mag, as a result of the Quality Control agent's test firing). This gives us even more confidence that JG is ever-increasing their attention paid to quality, and is a contributing reason to why the quality of JG AEGs gets better year after year.

Battery Charging Notice: To ensure safe battery charging, do NOT leave the battery in the crane stock when charging. Always remove the battery, place it on a safe, non-flammable surface, then charge the battery. Failure to do so may cause a fire/burn hazard to both the rear stock AND the battery/charger itself.

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.
