When using Magpul Sling Mount Kit (https://magpul.com/firearm-accessories/slings/sling-mount-kit-type-1.html?mp_global_color=118) with the KP-15 it is too short to accept a QD Swivel. This extender acts as a washer between the sling mount and the receiver, allowing swivels to mount correctly. The screw that comes with the kit may need to be threaded in, but will go without issue.
