CST K-Lug Rear Attachment allows a drop-in secondary rear action screw with the popular KRG Bravo chassis, providing rear support and two action screws for your barreled action, especially beneficial with free floating heavy or longer length barrels. No special inletting or gunsmithing needed with the KRG Bravo chassis and any stock system with compatible inletting.

New precision interface now built into the rear of all CST Rimfire Receivers using the #8 thread of our original Rear Tabs and locking surfaces built into the K-Lug itself. Can be removed or added at any time.

#8 Locking Fastener provided, uses the 1/4-28 button-head fastener of the KRG Bravo stock. Matches the rear contour of our CentriX-22 and CentriX-ELR Receivers, (corners will protrude slightly with the Class-X Receivers). Available silver or black.
