LBE Unlimited A2 Birdcage Flash Hider 5.56/.223 AR-15 4140 Steel

The LBE Unlimited ARA2FH A2 Birdcage flash hider delivers proven muzzle flash reduction for AR-15 platforms chambered in 5.56x45mm NATO and .223 Remington. This traditional A2-style flash suppressor maintains the classic profile while providing effective flash signature reduction during low-light shooting conditions.

What Makes This Different

Constructed from heat-treated 4140 steel with a durable black finish, this flash hider offers superior corrosion resistance compared to standard carbon steel alternatives. The precision-machined crown and flash-cutting slots ensure consistent performance across various ammunition weights. Unlike lightweight aluminum options, the 4140 steel construction withstands sustained rapid fire without degradation or loosening.

Field testing demonstrates effective flash suppression across grain weights from 55 to 77 grains, making it suitable for tactical applications, competitive shooting, and hunting scenarios. The steel construction maintains zero retention through temperature extremes and extended firing sessions. Law enforcement agencies rely on similar A2 designs for their proven reliability and consistent performance in adverse conditions.
