Corvus Defensio Anti-Rotation QD-Sling-Attach


In stock

SKU: CD-008 Category:


The Corvus Defensio Anti-Rotation Stock Cap Retainer Bolt Kit solves two problems that often occur when using the AUG professionally.  Because the original stock cap retainer bolt can be rotated around its axis, the sling can become twisted after repeated slinging and unslinging of the rifle.  This creates unpleasant pressure points on the shoulder and quick adjustable slings might also lose that function.  While the Corvus Defensio Anti-Rotation feature completely prevents twisting of the sling, the QD function allows for fast sling detachment, e.g. for disassembly and cleaning of the rifle.
NOTE: Twisting of the sling will only be prevented if the front sling mount has limited rotation as well.  This is achievable by mounting the front sling swivel to the limited rotation QD mounting point built into the Corvus Defensio A3 Receiver Rail 35 Slot.
