Sionics Weapon Systems is a fairly new AR rifle manufacturer that is committed to delivering the highest quality Mil-Spec no-nonsense guns at the lowest possible price. And judging by its SAR-15-QR10 rifle, I would say they have succeeded.
The staff and management at Sionics is made up of former military and law enforcement personnel who know what it means to depend on your weapon system. Josh Ellis, the owner of Sionics, has worked closely with many police armorers to ensure that his rifle meets their needs. It has been extensively tested and approved by the Tucson Police Department as a patrol rifle. According to Ellis, Sionics rifles are being used by federal agents as well as being currently evaluated by several law enforcement agencies.
The SAR-15 is a direct gas impingement 5.56mm NATO semi-auto rifle exhibiting above standard quality. The fit and finish and attention to detail are equivalent to what one would expect from a custom gun shop and with some extras as well.
