Jane’s reports that Jordan arms manufacturer KADDB will be manufacturing the LWRC International 6.8mm PSD sub-carbine and under license for use by royal protection units.
The PSD is in the PDW (Personal Defense Weapon) class of weapons. It has a very short 8″ barrel. To compensate for the short barrel it is chambered in 6.8mm SPC. Bigger heavier bullets can achieve greater energy in short barrels. KADDB plan on producing the PSDs both with the sub-carbine barrel and a longer carbine barrel.
Regardless of how limited its deployment will be this must be one of the first if not the first, 6.8mm weapons to be officially adopted by a nations armed forces.
KADDB may also produce the AR-10 style LWRC International Rapid Engagement Precision Rifle (REPR).
