The Knight's Armament Company 6×35mm PDW is an experimental personal defense weapon designed by Knight's Armament Company (KAC), firing a new 6mm cartridge optimized for short barrel weapons.
As with all personal defense weapons, the KAC PDW is intended to be compact and lightweight (similar to submachine guns), but have a longer useful range (out to the low end of combat rifle ranges, 250–300 m).
The KAC PDW combines new and off the shelf components in its design. The lower receiver, holding the magazine and trigger assembly, is essentially a shortened M16 rifle lower receiver,which makes the basic operating controls familiar to many potential users.
The cartridge, upper receiver, and operating mechanism are all new designs by KAC.
The KAC PDW uses a completely side-folding , unlike the M16 and M4 designs which have their main operating spring in a tube in the stock, and therefore can only partially telescope, and not fold sideways at all.
The KAC PDW is over 10 inches shorter (19.5" vs. 29.8" with stocks folded) and more than 1 pound lighter (4.5 lb vs. 6.3 lb) than the currently serviced M4 carbine, a carbine in service with every branch of the US Military, and the barrel has been lightened with a new dimpling process.
The KAC PDW has two gas pistons tapping hot gas from the barrel to operate its mechanism, located on the top left and right sides of the bolt carrier. The single mainspring is located on top, between the two gas pistons.
The KAC PDW fires a 6×35 mm cartridge, a full centimeter shorter than the western military standard 5.56×45mm NATO round. The 6mm bullet is slightly wider, and the standard 6×35mm bullet slightly heavier, than the standard 5.56mm bullet (65 grains (4.2 g) versus 62 grains (4.0 g)).
Fired from a 10-inch (250 mm) barrel, KAC claims that the 6×35mm cartridge reaches a muzzle velocity of 2,450 ft/s (750 m/s), slightly faster than the muzzle velocity of a 5.56 mm cartridge fired from a similarly short barrel. The larger diameter, shorter 6 mm cartridge is optimized for these shorter barrel lengths, and would perform less efficiently from rifle-length barrels. The round's muzzle energy is 831 ft·lbf (1,127 J) versus 792 ft·lbf (1,074 J) for a 5.56 mm bullet, again from the same 10" standard barrel.
