A1-Style Birdcage Flash Hider (6 Slots)

  • 1767


This is the classic A1 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. It has 6 evenly-space slots that allow ambient air to mix with the hot gases, cooling them and thereby reducing the visible flash.

If you want to shoot prone and minimize dust kick-up, you'll want to stick with the A2 flash hider which has a solid bottom.
