6061-T6 Aluminum Pillar and correct length #12-24 Stainless Steel Bolt for utilizing the rear action screw feature available with the CST Rimfire Receivers.  One Pillar and #12-24 Socket Head Screw provided.

Pillar contains grooves along its outside diameter for better bonding with bedding agent.  Pillar and screw of correct length for below-flush installation just behind the trigger assembly.

Brief Instructions for Installation:  With cavity provided via proper inletting to accept the barreled receiver and attached rear tab, the pillar's diameter will allow easy insertion into a 3/8" drilled hole lined up with center of the rear tab's threaded hole.  The length of the rear tab, (both a short and long rear tab are available), will determine the distance of the pillar from the rear of the trigger guard.  Once 3/8" hole is made, and release agent is applied to the #12-24 screw, the pillar can be glued in using the #12 screw to hold in place.
