Our take: The new Javelin Airsoft Works Full Metal EBB [Electric Blowback] M4A1 is a high-quality, high performance AEG. It is one of the most affordable blowback M4 Airsoft rifles on the market (most of the blowback M4s currently on the market are gas-powered, not electric) and performs on par with a rifle of this caliber.
Equipped with a high-torque motor and metal gearbox, the Javelin M4A1 EBB rifle is a high quality, high-performance Airsoft AEG that has been tuned to deliver OVER 400 FPS of power with 0.20g seamless BBs with great accuracy up to 100+ feet, all the while with realistic blowback action that kicks the ejection port open each time to deliver a satisfying 'clink' with every shot. The power combined with the electric blowback makes this rifle a PHENOMENAL all-around performance AEG!
The unique 5-point retractable rear stock features integrated rails for easy accessory attachment, and also has a special storage compartment which holds up to 2x CR123A batteries (for back-up use in your optics/tactical lasers and flashlights). The Javelin M4A1 EBB rifle offers an amazing value that is hard to beat, especially if you're looking for a blowback M4 rifle!

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.
