While the ACS now comes standard with the ACS QD Swivel Sling Mount, it can be added to either the right or left side of older models for use with push-button sling swivels. Heavy-duty black phosphatized steel construction easily installs with provided hardware.
Swivels not included.
Made in U.S.A.
NOTE: Many makes of push-button QD swivels will make some contact with the ACS's battery tubes. This is considered normal and acts as a 'limited-rotation' feature.
The ACS QD Swivel Mount is NOT compatible with the STR™ or UBR® Stocks.
