Accu-Shot TRG PRM BT12-QK ONLY TRG Stock modification required Black. 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).

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.
