The Barra 400e Gen 2 Polymer Full-Auto is the first fully electric full-auto BB rifle on the market, giving you a cutting-edge alternative to CO2. Powered by the included 11.1V Lithium Polymer battery, it delivers over 1,000 shots per charge and can send .177 caliber steel BBs downrange at speeds up to 440 FPS, with a blistering rate of fire of about 550 rounds per minute. Forget the limitations of CO2—this AEG platform keeps firing reliably across a wide range of temperatures without power drop-off.
Built tough with a CNC-machined aluminum receiver and handguard, the 400e Gen 2 also features a textured AR-style pistol grip and a custom 6-position adjustable buttstock. It’s designed for versatility, with M-LOK slots on the handguard for accessories, a long Picatinny rail for optics, and included flip-up front and rear sights (rear is windage adjustable). The 100-round magazine and included speedloader keep the fun going, while the ambidextrous select-fire switch lets you swap instantly between safe, semi-auto, and full-auto fire modes.
