SIONICS Weapon Systems has introduced a new Short Side Lever for their Ambidextrous Safety. The new lever is shorter on the ejection port side of the AR-15 to provide more clearance for the shooter’s trigger finger.
The new Short Side Lever will be standard equipment on all SIONICS rifles going forward or it can be purchased separately. It comes with a selector spring and detent when purchased separately.
They even copied the screw used by Colt for USGI guns.
