Echo1 Stag Arms Licensed STAG-15 M8A3 Airsoft AEG Rifle

The Echo1 STAG-15 M8A3 AEG Rifle features a free-floating 10-inch rail system and battle sights licensed by Troy Industries. The metal rails have more than 42 inches of rail space for an array of aftermarket accessories. For quick target acquisition, the Troy flip-up front and rear battle sights deploy within seconds and can be used with scopes without getting in the way. And the retractable crane stock sports an integrated layer of fabric for comfortable cheek weld. On the inside, Echo1 made sure to equip the M8A3 with a full metal Version 2 gearbox with 8mm bearings. An M120 spring with polycarbonate spring guide ensures respectable FPS, and a two-piece hop-up unit comes paired with Madbull bucking. In addition, this rifle comes with a rechargeable nunchuck battery, standard wall charger and steel flash hider.

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.
