KP 15 rectangular plug

This is a plug for the KP 15 Lower from KE Arms. There is a rectangular hole for attaching a sling or an M-loc QD sling attachment to the buttstock. If you only use one of these holes for a sling there is another on the opposite side.
Friction fit and very tight.
I made a blank plug plus a few others.
Modeled in Tinkercad so easy to add your own text/logo using the blank plug.
