This sling adapter replaces an AR stock by being screwed into the the receiver of a weapon in place of the buffer tube. The sling adapter comes with one QR sling swivel. It can only be used for those weapons where the buffer and spring are not necessary for cycling the action. It was specifically developed to work with Ordnance Group launchers such as the Tac-D and Tac-79.
The adapter is made of aluminum and has a knurled end for tightening.
When this accessory is used with a cartridge firearm, BATF rules regarding the overall length of the weapon must be observed. Please check with BATF if you have any questions.
