Trigger Pull: The Barra 400E Full Auto 50rds BB Rifle uses an electronically driven system, so the trigger feels light with a short travel. Expect a slight delay as the motor cycles the spring before each shot. Higher-voltage batteries reduce delay and help sustain consistent bursts.

Accuracy: At 30 feet, the Barra 400E Full Auto 50rds BB Rifle produces tight groupings in semi-auto. In full auto, controlled bursts keep patterns tight while delivering fast follow-up shots. Adjustable sights make it easy to zero for your preferred BB weight and distance.

Build Quality: Robust construction with a CNC-style metal handguard and receiver for durability. Polymer stock, grip, and sights help manage weight while staying field-tough. Overall fit and finish feel solid and confidence-inspiring.

Realism: AR-platform styling with functional controls (charging handle, selector, mag release, dust cover). The electric drive keeps operation smooth and consistent without CO2 variability.

Pros:

• Electric AEG system—no CO2 required and minimal temperature sensitivity.
• Semi & full-auto modes for versatile shooting.
• Sturdy metal construction with ample accessory rail options (Picatinny / M-LOK).
• Adjustable sights and ergonomic, adjustable stock.
• Reliable 50-round magazine for sustained strings.

Cons:

• Requires compatible LiPo battery/charger (sold separately).
• No blowback; prioritizes consistent AEG performance over recoil feel.

Comments: The Barra 400E Full Auto 50rds BB Rifle delivers a fast, CO2-free, full-auto experience with strong build quality and dependable accuracy. Ideal for backyard target sessions and enthusiasts who want electric reliability with AR-inspired ergonomics.
