The Wilson Combat Flash Hider A2 Birdcage (Wilson Combat part no. TR-GIFH) is a muzzle device cut to the classic USGI birdcage pattern, sized for .223 Remington/5.56 NATO rifles. Wilson Combat threads it 1/2×28, the standard AR-15 muzzle thread, so it’s a direct-fit swap on most 5.56 barrels. The open-slot birdcage design vents propellant gas through multiple ports as it exits the bore, the same venting approach used on the M16A2 and later M4-family rifles to cut visible muzzle flash. It’s a straightforward way to bring a familiar, mil-spec-style profile to a 5.56 build.
