The Sako TRG Rail Kit comes complete and ready to install on your TRG stock. The kit allows for the installation of either the Accu-Shot BT12 or BT12-QK Precision Rail Monopods (BT12-QK is shown but not included). Installation of the BT29 DOES require the temporary removal of the butt pad assembly and a second hole to be drilled, all of which can be accomplished with common hand tools. B&T Industries L.L.C. strongly recommends a competent Gunsmith install the BT29 TRG Rail Kit.
