fire control selector, with its lever located on the left side of the receiver wall, enables fully automatic fire (lever in the “C”-marked position), semi-automatic fire (“P”) and three-round burst fire mode (“S”). The selector can be operated with the safety either engaged or disabled. The burst mode is achieved through a ratcheting device on the left side of the receiver that interacts with the trigger group on the trigger-disconnector and hammer pins. Its location eliminates the need for an anti-pin walkout device, such as a Shepard's Crook on semi-auto AKs and extended auto sear spring on full-autos. It also has an advantage to the M16 Rifle's burst mode in that releasing the trigger in the middle of a burst (one-two shot fired instead of full three) causes the ratchet to reset making the next three-round burst a new, full one instead of a continuation of the previous. The PA md. 86 achieves burst fire in a very similar manner with ratcheting device on trigger-disconnector and hammer pins though simply has a standard AK selector switch with an additional notch for burst and still retains the Rate Reducer, which the Tantal lacks. The weapon is secured against misfires through a manually operated safety (whose lever, as in the AKM is located on the right side of the receiver), that disables the trigger bar and limits the movement of the bolt carrier. Sliding the safety selector to the top position (marked with a “Z” symbol) secures the weapon, lowering the lever down (“O” setting) disables the safety. The Tantal feeds from a double-column curved box magazine, made from a synthetic bakelite material or stamped metal, with a 30-round cartridge capacity. The cold hammer forged barrel has a chrome-plated bore with four right-hand grooves at a 200 mm twist rate. It is equipped with a multifunction muzzle brake that can be used to launch rifle grenades. The Tantal features a metal wire side-folding stock (folds to the right side), ended with a profiled shoulder pad. The rifle can also use a fixed wooden or synthetic buttstock designed for AKM or AK-74 rifles. Both the upper and lower handguard and pistol grip are fabricated from bakelite, although a limited number of Tantal-specific black polymer handguards and pistol grips have also been produced. Most handguards designed for use with the wz. 1996 Beryl assault rifle may also be installed on the Tantal. The rifle
