The weapon allows for a conventional 20 or 40 round box magazine fitting within the pistol grip and has a ambidextrous fire-select lever and rear cocking grip. It has an extendable stock and a folding front grip. It can be fired either one- or two-handed.
It fires at a maximum rate of 950 rpm using a open bolt gas system, similar to the company's G36. The ammunition is specific to the gun and designed for good penetration and low recoil. The 4.6 mm x 30 steel bullet weighs only 1.6 g and has a velocity of 725 m/sec with a muzzle energy of 420 joules. Despite the small calibre the bullet has better penetration characteristics than the 5.7 mm x 30 round used in the P90 at the weapon's maximum range of around 200 m.
