A2-Style Birdcage Flash Hider

This is the classic A2 birdcage muzzle device made at an ISO facility that does nothing but firearms parts. Not much else to say; this is designed to hide flash, not reduce recoil. 

The bottom area is solid to reduce dust kick-up when shooting prone. If you want a really old-school look and don't plan to shoot prone, you might be interested in the A1 version that has 6 slots evenly spaced all around.
