The flash hider has a slight taper at the front that supports a bayonet and a little further to the rear – six side ports arranged in pairs.

Internally the flash suppressor features threading at the muzzle used to screw-in a blank firing attachment.

Located mid-length on the flash hider is a cut-out with a ring retainer spring that secures a rifle grenade to the barrel.

The Beryl fires 5.56×45mm ammunition with a steel-core standard round, a tracer cartridge and a training slug, which are produced by Zakłady Metalowe Mesko in the town of Skarżysko-Kamienna.
