the front that supports a bayonet and a little further to the rear – six side ports arranged in pairs. These ports are placed asymmetrically around the circumference of the flash hider and stabilize the weapon during continuous fire. 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 receiver housing contains several modifications over the receiver of the wz. 1988 rifle. It uses a reinforced rear stock trunnion, adapted for the new shoulder stock and a top-mounted Picatinny rail for mounting optical sights. The side-folding tubular metal stock is coated with a thermal polymer shrink film. It has a metal shoulder stop covered with a rubber recoil pad. More recent models come with a collapsible stock (see picture of wz. 2004 model on right side of page). The standard lower handguard features an angled rib pattern designed to enhance gripping by the support hand. The rear of the handguard features two molded notches that enable the 40 mm wz. 1974 grenade launcher to be mounted under the barrel (early versions of the wz. 1996 lacked these notches, fitted instead with handguards with lateral grooves). Some Beryl handguards are equipped with short Picatinny rails and an integral vertical foregrip. The Beryl's sighting system is very similar to the setup used on the Tantal, it does however differ with the addition of twin cuts made into the sides of rear sight base that are used to fasten a bracket for mounting the following optical sights: the passive PCS-6 night sight, a CK-3 reflex optical collimator (red dot sight), LKA-4 telescopic sight and CWL-1 scope with integrated laser rangefinder. However, the most used additional sight for Beryl is EOTech 552 holographic weapon sight and PCS-5M passive night sight. PCS-6 and CWL-1 are introduced in small number. The weapon's unique magazine is molded from plastic and is not interchangeable with magazines from the kbk wz. 1988 Tantal. The Beryl has a long, trapezoid-shaped selector switch, similar to those found on the AK-47 or almost all of the AK series. 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.
