The Neopup PAW-20 is a grenade launcher designed by Tony Neophytou and as of 2015, is produced and marketed by Denel.
Overview
The PAW-20 is a hand-held, semi-automatic grenade launcher that fires a 20 mm point detonating round. It holds six rounds in a detachable rotary magazine, with an effective range of 300–400 meters. It was designed mainly as an anti-personnel grenade launcher for use against opposition closely grouped together or behind light cover. However, it is also compatible with less-than-lethal ammunition. The PAW-20 is in direct competition with the more complicated and expensive joint German-U.S. XM25 CDTE and Korean S&T Daewoo K11. The PAW-20 has attracted some criticism due to the location of the ejection port; these allegations have largely been addressed as the spent casings are ejected no closer to the operator's face than in a conventional assault rifle being fired from the left hand. Due to the unique location of the pistol gripon the side of the weapon, it can be fired from the left shoulder for a right-handed operator by simply placing the butt on the left shoulder, with no hand swapping necessary. 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. The right-handed location of the pistol grip also allows the weapon to recoil unimpeded into the shoulder of the operator, allowing for a much more manageable recoil than most weapons of this class. Moreover, the weapon uses the recoil to operate, instead of more traditional gas operated systems and is an interesting example of an inertial operated weapon.
20x42 mm cartridge
The 20x42 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, and a much flatter trajectory than the more common 40mm grenade launcher round. A number of less-than-lethal rounds are also available for the PAW-20.
