While the ACS and ACS-L now come standard with the Sling Mount Kit - Type 3, it can be added to either the right or left side of older models for use with push-button QD sling swivels. Heavy-duty black phosphatized steel construction easily installs with provided hardware.
Swivels not and buttstock are 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
