Our take: The JG M4 Adaptive Rail AEG is one of the highest-rated airsoft rifles we've EVER carried here at Airsoft Megastore, and for good reason. It is the quintessential "Player's AEG" - it comes with everything you need and nothing you don't. For the all-new enhanced production run model, JG has done the impossible. They've re-worked and improved what MANY players thought was already a PERFECT AEG.
JG has reinforced the build of the gearbox to withstand higher FPS while maintaining a high rate of fire; the gearbox works harmoniously with the newest version of JG's ultrahigh-torque motor to deliver OVER 800 ROUNDS PER MINUTE on full auto atOVER 400 FPS. The addition of a factory-installed tight bore barrel enhances accuracy greatly and is perhaps one of the best overall upgrades done to this JG M4.
The JG M4 Adaptive Rail Carbine comes equipped with full metal rails attached to its unique handguard, and also features a continuous top rail extending from the front sight to the rear flip-up sight. The fully modular M4 is one of the most versatile AEGs that JG manufactures. This airsoft rifle features a solid ABS plastic body, with a functional selector switch and magazine release. Topping the chronograph at over 450 FPS, this M4 has a muzzle velocity that overpowers the likes of $300-$450 Tokyo Marui and Classic Army AEGs. Its JG enhanced full metal gearbox & super high-torque motor set-up has been thoroughly designed to ensure that no matter WHERE you play, IF you play with this AEG rifle, it will dominate the Airsoft field or arena.
Also, the JG Airsoft M4 Adaptive Rail AEG Rifle (JG M4SS) features adjustable hop up, adjustable rear sights, and a rear-retractable 4-point 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.
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 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.
