The Neopup PAW-20 (Personal Assault Weapon, 20 mm) is a 20×42mm semi-automatic grenade launcher designed by Tony Neophytou and as of 2015, is produced and marketed by Denel.
It was designed mainly as an anti-personnel grenade launcher for use against opposition closely grouped together or behind light cover.
This allows the user the advantage of being able to fire from around or under cover, with little time required to change the grip on the weapon.
[3] The 20×42 mm cartridge was specifically developed for the PAW-20 by Denel PMP, decreasing the overall weight and size of the weapon, and enabling it to hold more rounds in the magazine, compared to weapons of similar purpose and design, such as the XM25 CDTE, which typically fire 25mm or larger grenades.
It has a muzzle velocity of 310 m/s (1,000 ft/s), and a much flatter trajectory than the more common 40 mm grenade launcher round.
