The small push pin is used to retain the forearm to the receiver on the 90 series of firearms. The QD sling pin is a great replacement item as it will allow the user to simply swap the push pin for the sling pin to allow a sling mounting location for a QD sling.

The sling pin can be installed on either the left or right side of the firearm effectively offering the user a true ambidextrous sling location. Made from fully hardened CNC'ed stainless steel. Each unit was engineered with a patent pending locking nut that once installed will not walk loose and is rock solid. This is simply the finest sling attachment design ever made and offered only here at HK Parts.
