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. Like our other monopods, it's constructed of the finest materials and built to the highest standards right here in the USA. Available in black only.
